c) The HCF of two numbers is 144 and their LCM is 288. If one of the number is 576, Find the other.

Answer 1

Step-by-step explanation:

hcf×lcm=1st no. ×2nd no.

=>144×288=576×x (as 2nd number be x)

=>x=144×288/576

=>144×144×2/144×2×2=x

=>x=144/2

=>x=72

THANK YOU.....I HOPE THIS WILL HELP YOU

Answer 2

Answer:

72

Step-by-step explanation:

let the unknown number be a

HCF X LCM = product of two number

144 X 288 = 576 X a

or, 144 X 288 / 576 = a

or, 41472 / 576 = a

a = 72
