Question

​First, look for any prime that divides________ of the numbers with________ no remainder. a remainder. Then​ divide, bringing down any numbers _______ not divisible divisible by the prime. Repeat this process until it is impossible to divide further​ - that​ is, until ________ not all of the numbers are there are no two numbers divisible by the same prime. Then the LCM is the product of all the primes and of the remaining numbers.

Answer 1

Explanation:

These steps are the steps involved in finding the LCM of two numbers.

• First, look for any prime that divides any of the numbers with no remainder.
• Then​ divide, bringing down any numbers not divisible by the prime.
• Repeat this process until it is impossible to divide further​ - that​ is, until there are no two numbers divisible by the same prime.
• Then the LCM is the product of all the primes and of the remaining numbers.

Example: Determine the LCM of 7 and 9

`\left|\begin{array}3&7&9\\--&--&--\\3&7&3\\&7&1\end{array}\right|`

The LCM of 7 and 9=3 X 3 X 7 X 1 =63
