Question

Hcf of 96 and128 by prime factorisation

Answer 1

the prime factorization of 96

96 = 2 × 2 × 2 × 2 × 2 the prime factorization of 125

125 = 5 × 5×5

the Hcf, multiply all the prime factors common to both numbers:

Therefore, HCF = 1

Answer 2

Answer:

ans: the HCF of 96 and 128 = 32

Step-by-step explanation:

The prime factors of 96 & 128 are:

96 = 2 X 2 x 2 x 2 x 2 x 3

128 = 2 x 2 x 2 x 2 x 2 x 2 x 2

Their HCF = 2 x 2 x 2 x 2 x 2

= 4 x 4 x 2

= 16 x 2 = 32

( hcf means highest common factors, take all the common factors for both the i,e 96 & 128 and multiple it)
