Given numbers are 638, 951, 57, 745

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

Apply this formula for all numbers.

Step1:

LCM(638, 951) = 606738

GCD(638, 951) = ( 638 x 951 ) / 606738

= 638 / 951

= 638

Step2:

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

= 1 / 57

= 1

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 638, 951, 57, 745 is 1
