Given numbers are 277, 390, 678, 638

The list of prime factors of all numbers are

Prime factors of 277 are 277

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 678 are 2 x 3 x 113

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 277, 390, 678, 638

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

Apply this formula for all numbers.

Step1:

LCM(277, 390) = 108030

GCD(277, 390) = ( 277 x 390 ) / 108030

= 277 / 390

= 277

Step2:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

Step3:

LCM(1, 638) = 638

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

= 1 / 638

= 1

So, Greatest Common Divisor of 277, 390, 678, 638 is 1
