GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 261) = 18531
GCD(639, 261) = ( 639 x 261 ) / 18531
= 639 / 261
= 639
Step2:
LCM(9, 832) = 7488
GCD(9, 832) = ( 9 x 832 ) / 7488
= 9 / 832
= 9
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 639, 261, 832, 556 is 1
