GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 627) = 50787
GCD(243, 627) = ( 243 x 627 ) / 50787
= 243 / 627
= 243
Step2:
LCM(3, 638) = 1914
GCD(3, 638) = ( 3 x 638 ) / 1914
= 3 / 638
= 3
Step3:
LCM(1, 572) = 572
GCD(1, 572) = ( 1 x 572 ) / 572
= 1 / 572
= 1
So, Greatest Common Divisor of 243, 627, 638, 572 is 1
