GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 394) = 125686
GCD(638, 394) = ( 638 x 394 ) / 125686
= 638 / 394
= 638
Step2:
LCM(2, 107) = 214
GCD(2, 107) = ( 2 x 107 ) / 214
= 2 / 107
= 2
Step3:
LCM(1, 859) = 859
GCD(1, 859) = ( 1 x 859 ) / 859
= 1 / 859
= 1
So, Greatest Common Divisor of 638, 394, 107, 859 is 1
