Question

Using prime factorisation find hcf and lcm of 168and 448?

Answer 1

Hiii friend,


Prime factorisation of 168 = 2 × 2 × 2 × 3 × 7



Prime factorisation of 448 = 2 × 2 × 2 × 2 × 2 × 2 × 7


LCM of 168 and 448 = 2 × 2 × 2 × 2 × 2 × 2 × 3 ×7 = 1344


HOPE IT WILL HELP YOU..... :-)

168=2×2×2×7×3
448=2×2×2×2×2×2×7
So, the HCF of 168,448=56.
the LCM of 168,448 =1344.
