Question

Find HCF of 48 and 28. Also find the HCF of 48 and the number obtained by finding their difference.

Answer 1

HCF of 48 and 28

$48=2\times 2\times 2\times 2\times 3$

$28=2\times 2\times 7$

HCF of $(48,28)=2\times 2=4$

HCF of (48, 48 – 28)

$48=2\times 2\times 2\times 2\times 3$

$20=2\times 2\times 5$

HCF of (48, 20) = 4
