Given numbers are 638, 957, 642, 268

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

Apply this formula for all numbers.

Step1:

LCM(638, 957) = 1914

GCD(638, 957) = ( 638 x 957 ) / 1914

= 638 / 957

= 638

Step2:

LCM(319, 642) = 204798

GCD(319, 642) = ( 319 x 642 ) / 204798

= 319 / 642

= 319

Step3:

LCM(1, 268) = 268

GCD(1, 268) = ( 1 x 268 ) / 268

= 1 / 268

= 1

So, Greatest Common Divisor of 638, 957, 642, 268 is 1
