Given numbers are 438, 774, 865, 250

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 865 are 5 x 173

Prime factors of 250 are 2 x 5 x 5 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 438, 774, 865, 250

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

Apply this formula for all numbers.

Step1:

LCM(438, 774) = 56502

GCD(438, 774) = ( 438 x 774 ) / 56502

= 438 / 774

= 438

Step2:

LCM(6, 865) = 5190

GCD(6, 865) = ( 6 x 865 ) / 5190

= 6 / 865

= 6

Step3:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

So, Greatest Common Divisor of 438, 774, 865, 250 is 1
