Question

the HCF of two number is
144 and their LCM is 2880 if one of the number is 720 find the other number?

Answer 1

HCF*LCM =PRODUCT OF TWO NUMBERS
144* 2880 = 720*x
x= 144* 2880/720 =148

Answer 2

Given :

HCF = 144

LCM = 2880

One of the two nos. = 720

Formula :

$\bf\purple{\fbox{Product\:of\:the\: numbers\:= HCF×LCM}}$

Assuming :

Other number = x

Solution :

Product of the numbers = HCF × LCM

=> 720 × x = 144×2880

=> x = 144×2880/720

=> x = 576

Answer :

• 576 is the other number.
