Question

What is the LCM of 9 and 12?

Answer 1

A = `3^2 * 2^2`
= `9*4`
= `36`

Explanation:

1. Find the Prime Decomposition (`Pd`) of the two numbers

= `Pd (9)` = `3^2`
= `Pd(12)` = `2^2 * 3`

1. Find the product of the number with the greatest exponent - for example: `3^2 > 3`

= `3^2 * 2^2`
= `36`
