Question

what is the smallest multiple of 45 90 and 180​

Answer 1

Answer:

What are the Multiples of 45?

To get multiples of a number, we need to multiply natural numbers with integers. For example, 45 × 2 = 90, 90 is a multiple of 45 and also a multiple of 5. Now let us consider the first 5 multiples of 45,

45 × 1 = 45

45 × 2 = 90

45 × 3 = 135

45 × 4 = 180

45 × 5 = 225

According to this, the first five multiples of 45 you just learned are 45, 90, 135, 180, 225.
