Question

Using prime Factorization find the HCF and LCM of :36, 84​

Answer 1

Step-by-step explanation:

Answer

Prime factorization:

36 = 22 × 3.

84 = 22 × 3 × 7.

HCF = product of smallest power of each common prime factor in the numbers = 22 × 3 = 12.

LCM = product of greatest power of each prime factor involved in the numbers = 22 × 32 × 7 = 252.
