Finding GCD of 255, 570, 661 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(255, 570) = 9690

GCD(255, 570) = ( 255 x 570 ) / 9690

GCD(255, 570) = 145350 / 9690

GCD(255, 570) = 15


Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 661

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(15, 661) = 9915

GCD(15, 661) = ( 15 x 661 ) / 9915

GCD(15, 661) = 9915 / 9915

GCD(15, 661) = 1

GCD of 255, 570, 661 is 1
