## What are the common multiples of 3 and 6?

In arithmetic the least common multiple (LCM) of two numbers a and b is the smallest positive integer that is a multiple of both a and b. So, the multiples of 3 are : 3, 6, 9, 12, … The multiples of 6 are : 6, 12, … So 12 is the first , that is least, common multiple between 3 and 6.

## What do you notice about multiples of 3?

Patterns in Multiplying by 3’s Multiples of 3 have a pattern of 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 in the ones place. Every other multiple of 3 is even. The digits in multiples of 3 add up to a multiple of 3 (36 = 3 + 6, 111 = 1 + 1 + 1, etc.)

## IS 144 a perfect square?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 144 is 12. Therefore, the square root of 144 is an integer, and as a consequence 144 is a perfect square.

## What two factors can be multiplied to result in a product of 126?
