Question

find LCM and HCF of 12 and 15 by prime factorization method​

Answer 1

SOLUTION :

SOLUTION :12 = 2 x 2 x 3 = 2² × 3¹

SOLUTION :12 = 2 x 2 x 3 = 2² × 3¹15 = 3 x 5 = 3¹ × 5¹

SOLUTION :12 = 2 x 2 x 3 = 2² × 3¹15 = 3 x 5 = 3¹ × 5¹21 = 3 x 7 = 3¹ × 7¹

SOLUTION :12 = 2 x 2 x 3 = 2² × 3¹15 = 3 x 5 = 3¹ × 5¹21 = 3 x 7 = 3¹ × 7¹L.C.M of 12, 15 and 21 = 420.

SOLUTION :12 = 2 x 2 x 3 = 2² × 3¹15 = 3 x 5 = 3¹ × 5¹21 = 3 x 7 = 3¹ × 7¹L.C.M of 12, 15 and 21 = 420.H.C.F of 12, 15 and 21 = 3.

SOLUTION :12 = 2 x 2 x 3 = 2² × 3¹15 = 3 x 5 = 3¹ × 5¹21 = 3 x 7 = 3¹ × 7¹L.C.M of 12, 15 and 21 = 420.H.C.F of 12, 15 and 21 = 3.17 = 1 x 17.

SOLUTION :12 = 2 x 2 x 3 = 2² × 3¹15 = 3 x 5 = 3¹ × 5¹21 = 3 x 7 = 3¹ × 7¹L.C.M of 12, 15 and 21 = 420.H.C.F of 12, 15 and 21 = 3.17 = 1 x 17.23 = 1 x 23.
