Given numbers are 251, 749, 631, 747

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

Apply this formula for all numbers.

Step1:

LCM(251, 749) = 187999

GCD(251, 749) = ( 251 x 749 ) / 187999

= 251 / 749

= 251

Step2:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

Step3:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

So, Greatest Common Divisor of 251, 749, 631, 747 is 1
