FAQs on Be My Multiple, I`ll be Your Factor - 2 Class 5 Worksheet Maths Chapter 6

1. What is the concept of being a multiple or a factor in mathematics?
Ans. In mathematics, being a multiple or a factor refers to the relationship between numbers. A multiple is a number that can be divided evenly by another number, while a factor is a number that divides another number evenly without leaving a remainder. For example, 12 is a multiple of 3 because it can be divided evenly by 3, and 3 is a factor of 12 because it divides 12 evenly.
2. How can I determine if a number is a multiple of another number?
Ans. To determine if a number is a multiple of another number, you can check if it can be divided evenly by the other number. If the division results in a quotient without any remainder, then the number is a multiple. For example, to check if 15 is a multiple of 5, divide 15 by 5. Since 15 ÷ 5 = 3 with no remainder, 15 is a multiple of 5.
3. What is the difference between a multiple and a factor?
Ans. The difference between a multiple and a factor lies in their relationship to each other. A multiple is a number that can be divided evenly by another number, while a factor is a number that divides another number evenly without leaving a remainder. In simpler terms, a multiple is the result of multiplying a number by another number, while a factor is a number that divides another number without leaving a remainder.
4. Can a number be both a multiple and a factor of another number?
Ans. Yes, a number can be both a multiple and a factor of another number. This happens when two numbers have a common factor. For example, consider the numbers 6 and 12. 6 is a factor of 12 because it divides 12 evenly, and 12 is a multiple of 6 because it can be divided evenly by 6. Therefore, in this case, 6 is both a factor and a multiple of 12.
5. How can I find the common factors of two numbers?
Ans. To find the common factors of two numbers, you can list down all the factors of both numbers and identify the ones that appear in both lists. The common factors are the numbers that divide both numbers evenly without leaving a remainder. For example, to find the common factors of 12 and 18, list down the factors of both numbers: 12 (1, 2, 3, 4, 6, 12) and 18 (1, 2, 3, 6, 9, 18). The common factors are 1, 2, 3, and 6.
