What Are the Multiples of 72?

Multiples are numbers that we get when we multiply one whole number by another whole number. 72 x any whole number = A multiple of 72

We get the nth multiple of 72 by doing 72 x n. The 12thmultiple of 72 is 72 x 12 = 864.
We get the successive multiples of 72 by skip counting or repeated addition. 72 + 72 + 72 + 72 = 4 x 72 = 288 and the 5th multiple of 72 is 288 + 72 = 360.
All the multiples of 72 are also the multiples of its factors. For example, 72 = 8 x 9. 8 and 9 are factors of 72. 72 is a multiple of 8 as well as 9.

Important Notes

A number can have infinite multiples. The multiples of 72 are infinite.
Multiply 72 by any whole number and get the multiples of 72.
Multiples of 72 are obtained by repeatedly adding 72.

Tips and Tricks

To check if a number is a multiple of 72, divide it by 72.
Add 72 to a multiple of 72 to get the successive multiple.
72 × whole number = whole number × 72 = multiple of 72. Example, 72 × 8 = 8 × 72

Example 1: Alex gives a handshake to every 72nd visitor in his restaurant. If he has shaken hands 22 times now, how many visitors has he got so far?

Solution: On the first handshake, the visitors he had 1 × 72 = 72

On the 10thshake, the visitors = 10 × 72 = 720

On the 22ndhandshake, the visitors he had = 22 × 72 = 1584

He has got 1584 visitors.
Example 2: Sam builds a rectangle using blocks of 8 rows and 9 columns. If he raises this rectanglular tower by 15 more layers, how many blocks will be there in all?

Solution: The number of blocks in the rectangle = 8 rows × 9 columns

8 × 9 = 72 blocks

If there are 15 more layers, then the number of blocks is 15 layers × 72 blocks

15 × 72 = 1080 blocks
