GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 116) = 1276
GCD(638, 116) = ( 638 x 116 ) / 1276
= 638 / 116
= 638
Step2:
LCM(58, 388) = 11252
GCD(58, 388) = ( 58 x 388 ) / 11252
= 58 / 388
= 58
Step3:
LCM(2, 570) = 570
GCD(2, 570) = ( 2 x 570 ) / 570
= 2 / 570
= 2
So, Greatest Common Divisor of 638, 116, 388, 570 is 2
