FAQs on Be My Multiple, I`ll be Your Factor Video Lecture - Mathematics for Class 5: NCERT

1. What is the relationship between a multiple and a factor in mathematics?
Ans. A multiple of a number is the result of multiplying that number by another whole number, while a factor of a number is a number that divides the original number without leaving a remainder. In simpler terms, if a number A is a multiple of another number B, then B is a factor of A.
2. How can multiples and factors be used in real-life scenarios?
Ans. Multiples and factors are commonly used in everyday situations like calculating time, money, and measurements. For example, when calculating the total cost of buying multiple items of the same price, you are essentially finding the multiple of the item price. On the other hand, finding factors of a number can help in simplifying fractions or determining the dimensions of a rectangular area.
3. 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. For example, if we take the number 6, it is a multiple of 2 (3 x 2 = 6), and it is also a factor of 12 (12 ÷ 2 = 6). This shows that multiples and factors are closely related concepts in mathematics.
4. How can one determine if a number is a multiple of another number without dividing?
Ans. To determine if a number is a multiple of another number without dividing, you can check if the last digit of the number in question matches the last digit of the potential multiple. For example, if you want to see if 24 is a multiple of 8, you can look at the last digit of both numbers (4 and 8), and if 8 is a factor of 24, then 24 is a multiple of 8.
5. Are there any shortcuts or tricks to quickly identify multiples and factors of numbers?
Ans. Yes, there are some shortcuts and tricks to quickly identify multiples and factors of numbers. For instance, for even numbers, any number ending in 0, 2, 4, 6, or 8 is a multiple of 2. Similarly, for multiples of 5, the last digit must be either 0 or 5. These simple rules can help in quickly identifying multiples and factors of numbers without having to perform lengthy calculations.
