Question

Find lcm and hcf of 30, 34, 56 using fundamental theorem of arithmetic

Answer 1

Answer:

Fundamental theorem of arithmetic applies only for two numbers.

Therefore, HCF and LCM of these numbers can be found through prime factorisation method.

30= 2×3×5

34= 2×17

56= 2^3 × 7

Therefore HCF= 2 and

HCF= 2 and LCM = 14280
