GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(860, 638) = 274340
GCD(860, 638) = ( 860 x 638 ) / 274340
= 860 / 638
= 860
Step2:
LCM(2, 372) = 372
GCD(2, 372) = ( 2 x 372 ) / 372
= 2 / 372
= 2
Step3:
LCM(2, 478) = 478
GCD(2, 478) = ( 2 x 478 ) / 478
= 2 / 478
= 2
So, Greatest Common Divisor of 860, 638, 372, 478 is 2
