GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 870) = 9570
GCD(638, 870) = ( 638 x 870 ) / 9570
= 638 / 870
= 638
Step2:
LCM(58, 782) = 22678
GCD(58, 782) = ( 58 x 782 ) / 22678
= 58 / 782
= 58
Step3:
LCM(2, 683) = 1366
GCD(2, 683) = ( 2 x 683 ) / 1366
= 2 / 683
= 2
So, Greatest Common Divisor of 638, 870, 782, 683 is 1
