Question

Find the LCM of the given numbers by prime factorisation method 24,28 and 196

Answer 1

L.C.M of 24, 28 and 196 by prime factorization method :

➡ 24 = 2 × 2 × 2 × 3

➡ 28 = 2 × 2 × 7

➡ 196 = 2 × 2 × 7 × 7

LCM :

$= {2}^{3} \times {7}^{2} \times 3$

= 8 × 49 × 3

= 1,176.

Hence,

1,176 is the LCM of 24, 28 and 196.

Answer 2

Answer:

L.C.M of 24, 28 and 196 by prime factorization method :

➡ 24 = 2 × 2 × 2 × 3

➡ 28 = 2 × 2 × 7

➡ 196 = 2 × 2 × 7 × 7

LCM :

= {2}^{3} \times {7}^{2} \times 3=23×72×3

= 8 × 49 × 3

= 1,176.

Hence,

1,176 is the LCM of 24, 28 and 196.
