Answer 2

Answer:

The LCM of 56 and 84​ is 168.

Step-by-step explanation:

Given: The numbers are 56 and 84​.

We have to find the LCM of the above numbers.

We are solving in the following way:

We have,

The numbers are 56 and 84​.

First, we will find the prime factors for each number.

Prime Factorization of 56 is:

$2 \times 2 \times 2 \times 7 => 2^3 \times 7^1$

Prime Factorization of 84 is:

$2 \times 2 \times 3 \times 7 => 2^2 \times 3^1 \times 7^1$

For each prime factor, we will find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is:

2, 2, 2, 3, 7

Multiplying these factors together to find the LCM:

$LCM = 2 \times 2 \times 2 \times 3 \times 7 = 168$
