Question

first number is 6 and second number is 24 if lcm of number is 36 find their h.c.f?

Answer 1

product of the numbers= LCM ×HCF
6×24 =36×Hcf
Hcf=6×24/36
=24/6
=4
hcf=4 is answer obtained

Answer 2

HCF = Highest Common factor

LCM = Least Common Multiple




We know that => 1st number × 2nd number = HCF × LCM

By using this formula, we will solve the sum :-


6 × 24 = HCF × 36

144 = HCF × 36

HCF = $\frac{144}{36}$

HCF = 4




$\therefore{}$ HCF is 4
