Question

the lcm of two numbers is 12 times to their hcf the addition of their lcm and hcf is 403.if one no is 93 find out the second number

Answer 1

let the hcf be x

therefore LCM=12x

12x+x=403

x=403/13

=31

therefore LCM=31 and hcf=372

LCM*hcf=product of number

372*31=93*y

=y=31*12*31/93

=124
