Step-by-step explanation:

Answer 2

Answer:

The lcm of 20 and 25​ is 100.

Step-by-step explanation:

Given: The numbers are 20 and 25​.

We have to find the lcm of the above numbers.

• As we know, the lcm is the least number, which is exactly divisible by two or more numbers.

We are solving in the following way:

We have,

The numbers are 20 and 25​.

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

Prime Factorization of 20 is:

$2 \times 2 \times 5 => 2^2 \times 5^1$

Prime Factorization of 25 is:

$5 \times 5 => 5^2$

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 list is:

2, 2, 5, 5

Multiplying these factors together to find the LCM.

$LCM = 2 \times 2 \times 5 \times 5 = 100$

Therefore,

LCM(20, 25) = 100
