Given numbers are 626, 420, 557, 905

The list of prime factors of all numbers are

Prime factors of 626 are 2 x 313

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 557 are 557

Prime factors of 905 are 5 x 181

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

Given numbers are 626, 420, 557, 905

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

Apply this formula for all numbers.

Step1:

LCM(626, 420) = 131460

GCD(626, 420) = ( 626 x 420 ) / 131460

= 626 / 420

= 626

Step2:

LCM(2, 557) = 1114

GCD(2, 557) = ( 2 x 557 ) / 1114

= 2 / 557

= 2

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 626, 420, 557, 905 is 1
