Question

find LCM of 435,725​

Answer 1

Answer:

145 is the LCM of 435,725

Answer 2

Answer:

The lcm of 435 and 725 is 2175.

Step-by-step explanation:

Given: The numbers are 435 and 725.

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 435 and 725.

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

Prime Factorization of 435 is:

$3 \times 5 \times 29 => 3^1 \times 5^1 \times 29^1$

Prime Factorization of 725 is:

$5\times 5 \times 29 => 5^2 \times 29^1$

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 list is:

3, 5, 5, 29

Multiplying these factors together to find the LCM:

$LCM = 3 \times 5 \times 5 \times 29 = 2175$

Therefore,

LCM(435, 725) = 2175
