Given numbers are 638, 691, 985, 774

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

Apply this formula for all numbers.

Step1:

LCM(638, 691) = 440858

GCD(638, 691) = ( 638 x 691 ) / 440858

= 638 / 691

= 638

Step2:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

Step3:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

So, Greatest Common Divisor of 638, 691, 985, 774 is 1
