Multiples and Factors PPT, Part 2: Interpretation of Examples

At the sports meeting, students from two classes formed the following two formations. How many people are there in each class?

There are 9 people in each row, 4 rows in total.

9×4=36 (people)

There are 5 people in each row, 7 rows in total.

5×7=35 (people)

Recognize it.

9×4=36, 36 is a multiple of 9 and 4, and 9 and 4 are factors of 36.

According to 5×7=35, can you tell which number is a multiple of which number and which number is a factor of which number?

According to 5×7=35, we can know that 35 is a multiple of 5 and 7, and 5 and 7 are factors of 35.

We study multiples and factors only within the range of natural numbers (other than zero).
