Question

Using prime factorisation find the h .c.f of 30,72,432

Answer 1

30=2×3×5
72=2×2×2×3×3
432=2×2×2×2×3×3×3

common= 2×3=6

so hcf is 6

i think it will correct.

Answer 2

Hey There,

The prime factorization of the given numbers are:

$30=2\times 3 \times 5 \\ \\ 72 = 2^3 \times 3^2 \\ \\ 432 = 2^4 \times 3^3$

Now, we have to take the highest common factor. 

So,

$HCF = 2 \times 3 \\ \\ \implies \boxed{HCF=6}$


Thus, the answer is 6.
