Question

Find the HCF of the numbers whose product is 8000 and their LCM is 800

Answer 1

according to the formulae
lcm ×hcf =a×b
800×hcf=8000
hcf = 8000÷ 800
hcf = 10

Answer 2

1. Let the two numbers be x and y Now, if xy is 8000 and their L.C.M is 800. Therefore, the H.C.F of x and y = 8000/800 => 10
