Test: Factors and Multiples- 1 - Question 1

Which one of the following is a factor of 45 and not a multiple of 3?

Detailed Solution for Test: Factors and Multiples- 1 - Question 1

Factors of 45: 1, 3, 5, 9, 15, 45
Multiples of 3: 3, 6, 9, 12, 15, 18.....
So, 5 is a factor of 45 but not a multiple of 3.

Test: Factors and Multiples- 1 - Question 2

Which one of the following is a multiple of 2 but not a factor of 8?

Detailed Solution for Test: Factors and Multiples- 1 - Question 2

Factors of 8: 1, 2, 4, 8
Multiples of 2: 2, 4, 6, 8, 10, 12.....
So, 6 is a multiple of 2 but not a factor of 8.

Test: Factors and Multiples- 1 - Question 3

What are the multiples of 16 between 40 and 90?

Detailed Solution for Test: Factors and Multiples- 1 - Question 3

48 = 3 × 16 is a multiple of 16.
64 = 4 × 16 is a multiple of 16.
80 = 5 × 16 is a multiple of 16.
44 = 2 × 2 × 11 is not a multiple of 16.
42 = 6 × 7 is not a multiple of 16.
66 = 3 × 2 × 11 is not a multiple of 16.
86 = 2 × 43 is not a multiple of 16.
46 = 2 × 23 is not a multiple of 16.
68 = 2 × 2 × 17 is not a multiple of 16.
88 = 2 × 2 × 2 × 11 is not a multiple of 16.

Test: Factors and Multiples- 1 - Question 4

What is the seventh multiple of 9?

Detailed Solution for Test: Factors and Multiples- 1 - Question 4

To find the seventh multiple of 9, we multiply 9 by 7:

9 × 7 = 63

So, the seventh multiple of 9 is 63.

Therefore, the correct answer is D: 63.

Test: Factors and Multiples- 1 - Question 5
Write all the factors of 24.
Detailed Solution for Test: Factors and Multiples- 1 - Question 5

The factors of 24 are the numbers that divide 24 exactly without leaving a remainder. To find all the factors, list the pairs of numbers that multiply to give 24:

  • 1 × 24 = 24
  • 2 × 12 = 24
  • 3 × 8 = 24
  • 4 × 6 = 24

Thus, the complete list of factors is [1, 2, 3, 4, 6, 8, 12, 24].

Test: Factors and Multiples- 1 - Question 6
Every number is a multiple of:
Detailed Solution for Test: Factors and Multiples- 1 - Question 6
  • Option A (1) is correct.
  • Multiplying any number by 1 leaves it unchanged.
  • A multiple is a value you get by multiplying two whole numbers.
  • Every number can be expressed as itself times 1, so 1 divides all numbers.
Test: Factors and Multiples- 1 - Question 7
What is a factor of 30?
Detailed Solution for Test: Factors and Multiples- 1 - Question 7

A factor of 30 divides it exactly. Among the options, 3 and 5 do so:

  • 30 ÷ 3 = 10
  • 30 ÷ 5 = 6

Since both are correct but only one can be chosen, 3 is selected as the answer.

Test: Factors and Multiples- 1 - Question 8
Which of the following is a multiple of 7?
Detailed Solution for Test: Factors and Multiples- 1 - Question 8

To determine which number is a multiple of 7, we can divide each option by 7 and check if the result is a whole number.

  • Option A: 14 ÷ 7 = 2 (a whole number)
  • Option B: 15 ÷ 7 ≈ 2.14 (not a whole number)
  • Option C: 16 ÷ 7 ≈ 2.28 (not a whole number)
  • Option D: 18 ÷ 7 ≈ 2.57 (not a whole number)

Only option A results in a whole number when divided by 7, making it the correct answer.

Test: Factors and Multiples- 1 - Question 9
Which of these numbers is NOT a factor of 20?
Detailed Solution for Test: Factors and Multiples- 1 - Question 9

A factor of 20 must divide it exactly without leaving a remainder. Checking each option:

  • 20 ÷ 4 = 5 (Exact)
  • 20 ÷ 5 = 4 (Exact)
  • 20 ÷ 6 ≈ 3.333... (Not exact)
  • 20 ÷ 10 = 2 (Exact)

Thus, 6 is not a factor of 20.

Test: Factors and Multiples- 1 - Question 10
What is a multiple of 6?
Detailed Solution for Test: Factors and Multiples- 1 - Question 10
A multiple of 6 is obtained by multiplying it by another whole number. 6 × 2 = 12.
