• we find factors of  $25,40,120$

• Factors of $25=5\times 5$

• Factors of $40=2 \times 2 \times2\times5$

• Factors of $120=2 \times 2\times3 \times 5$

• $L C M=2 \times 2 \times 2 \times5 \times 5 \times3\times 3$

       $LCM\ = 600$

Hence . LCM of $25,40,120$  is $600$.

Answer 2

Given,

LCM of $25,40,120$

We have to find the LCM of given numbers

First we have to find the prime factors of each number

After that we have to tale least common factors of that numbers

$25=5\times5$

$40=5\times2\times2\times2$

$120=3\times 2\times2\times 5\times2$

LCM of  $25,40,120$ $= 5\times5\times4\times2\times3$

$= 600$

Therefore, the LCM of  $25,40,120$ is $600$.
