Question

If HCF of two numbers is 145 and their LCM is 2175. If one number is 72

Answer 1

let us assume that other no. is x
we know that
              ⇒  hcf × lcm=product of 2 numbers
              ⇒  145×2175=72 × x
              ⇒x=145×2175/72
             
there is some mistake in the question simplify is not happening to find the other no.
