Finding GCD of 153, 221, 631 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(153, 221) = 1989
GCD(153, 221) = ( 153 x 221 ) / 1989
GCD(153, 221) = 33813 / 1989
GCD(153, 221) = 17
Step2:
Here we consider the GCD from the above i.e. 17 as first number and the next as 631
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(17, 631) = 10727
GCD(17, 631) = ( 17 x 631 ) / 10727
GCD(17, 631) = 10727 / 10727
GCD(17, 631) = 1
GCD of 153, 221, 631 is 1
