Question

L. C. M. in prime factorization method 42,36and21​

Answer 1

Answer:

the answer is coming 31752

Answer 2

Solution:-

Hey mate here is your answer

$3 |42 \: 36 \: 21|$

$7 |14 \: 12 \: 7|$

$2 |2 \: 12 \: 1|$

$|1 \: 6 \: 1|$

Therefore,

L. C. M of 42,36 and 21 is 3x7x2x1x6=252

L.C.M by Prime factorization method

$42 = 7 \times 3 \times 2$

$36 = 3 \times 3 \times 2 \times 2$

$21 = 7\times 3$

$7 \times 3 \times 3 \times 2 \times 2 = 252$

Hence proved :)
