GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(638, 774) = 246906

GCD(638, 774) = ( 638 x 774 ) / 246906

= 638 / 774

= 638

Step2:

LCM(2, 982) = 982

GCD(2, 982) = ( 2 x 982 ) / 982

= 2 / 982

= 2

Step3:

LCM(2, 260) = 260

GCD(2, 260) = ( 2 x 260 ) / 260

= 2 / 260

= 2

So, Greatest Common Divisor of 638, 774, 982, 260 is 2
