Question

18. The product of two numbers is 2560 and their LCM is 320. Find their HCF​

Answer 1

Answer:

There's an identity

Product of two numbers = LCM * HCF

By substituting given values in identity

We get,

2560 = 320*HCF

HCF = 2560/320

HCF = 8

Therefore HCF of the two numbers is 8

Answer 2

Answer:

as we know that product of two no. = product of their hcf and lcm.

then, let the no. be a and b .

so , a × b = lcm (a, b) × hcf ( a,b).

since .. a× b = 2560.

then , 2560 = 320 × hcf ( a ,b).

➖) hcf (a, b) = 2560 / 320 = 8 .

hence their hcf = 8 .
