Question

if the LCM of two numbers is 253 and HCF is 131 and the first number is 917 which is the second number

Answer 1

$Heya$‼

As we know,
HCF ( a , b ) × LCM ( a , b ) = a × b

Given that, one number is 917. And we have to find the other number. So, let other number be a.

According to the question,
HCF ( 917 , a ) × LCM ( 917 × a ) = 917 × a
131 × 253 = 917a
a = 131 × 253 / 917
a = 33143 / 917
a = 36.14
