GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 634) = 405126
GCD(639, 634) = ( 639 x 634 ) / 405126
= 639 / 634
= 639
Step2:
LCM(1, 883) = 883
GCD(1, 883) = ( 1 x 883 ) / 883
= 1 / 883
= 1
Step3:
LCM(1, 218) = 218
GCD(1, 218) = ( 1 x 218 ) / 218
= 1 / 218
= 1
So, Greatest Common Divisor of 639, 634, 883, 218 is 1
