Given numbers are 638, 556, 427, 260
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 556) = 177364
GCD(638, 556) = ( 638 x 556 ) / 177364
= 638 / 556
= 638
Step2:
LCM(2, 427) = 854
GCD(2, 427) = ( 2 x 427 ) / 854
= 2 / 427
= 2
Step3:
LCM(1, 260) = 260
GCD(1, 260) = ( 1 x 260 ) / 260
= 1 / 260
= 1
So, Greatest Common Divisor of 638, 556, 427, 260 is 1
