GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(683, 639) = 436437
GCD(683, 639) = ( 683 x 639 ) / 436437
= 683 / 639
= 683
Step2:
LCM(1, 625) = 625
GCD(1, 625) = ( 1 x 625 ) / 625
= 1 / 625
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 683, 639, 625, 221 is 1
