GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 129) = 82302
GCD(638, 129) = ( 638 x 129 ) / 82302
= 638 / 129
= 638
Step2:
LCM(1, 513) = 513
GCD(1, 513) = ( 1 x 513 ) / 513
= 1 / 513
= 1
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 638, 129, 513, 836 is 1
