Given numbers are 275, 956, 880, 638

The list of prime factors of all numbers are

Prime factors of 275 are 5 x 5 x 11

Prime factors of 956 are 2 x 2 x 239

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 275, 956, 880, 638

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

Apply this formula for all numbers.

Step1:

LCM(275, 956) = 262900

GCD(275, 956) = ( 275 x 956 ) / 262900

= 275 / 956

= 275

Step2:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 275, 956, 880, 638 is 1
