GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 356) = 113564
GCD(638, 356) = ( 638 x 356 ) / 113564
= 638 / 356
= 638
Step2:
LCM(2, 134) = 134
GCD(2, 134) = ( 2 x 134 ) / 134
= 2 / 134
= 2
Step3:
LCM(2, 458) = 458
GCD(2, 458) = ( 2 x 458 ) / 458
= 2 / 458
= 2
So, Greatest Common Divisor of 638, 356, 134, 458 is 2
