Finding GCD of 639, 756, 280 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(639, 756) = 53676
GCD(639, 756) = ( 639 x 756 ) / 53676
GCD(639, 756) = 483084 / 53676
GCD(639, 756) = 9
Step2:
Here we consider the GCD from the above i.e. 9 as first number and the next as 280
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(9, 280) = 2520
GCD(9, 280) = ( 9 x 280 ) / 2520
GCD(9, 280) = 2520 / 2520
GCD(9, 280) = 1
GCD of 639, 756, 280 is 1
