Answer 2

Answer:

The lcm of 15, 25, and 30​ is 150.

Step-by-step explanation:

The numbers are 15, 25, and 30​.

We have to find the lcm of the above numbers.

• As we know that lcm is the smallest common multiple of two or more numbers.

We are solving in the following way:

We have,

The numbers are 15, 25, and 30​.

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

Prime Factorization of 15 is:

$3 \times 5 => 3^1 \times 5^1$

Prime Factorization of 25 is:

$5 \times 5 => 5^2$

Prime Factorization of 30 is:

$2 \times 3 \times 5 => 2^1 \times 3^1 \times 5^1$

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, 3, 5, 5

Multiplying these factors together to find the LCM:

$LCM = 2 \times 3 \times 5 \times 5 = 150$

Therefore,

LCM(15, 25, 30) = 150
