Given numbers are 638, 617, 598, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 617) = 393646
GCD(638, 617) = ( 638 x 617 ) / 393646
= 638 / 617
= 638
Step2:
LCM(1, 598) = 598
GCD(1, 598) = ( 1 x 598 ) / 598
= 1 / 598
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 638, 617, 598, 129 is 1
