Given numbers are 805, 128, 908, 630

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 908 are 2 x 2 x 227

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 805, 128, 908, 630

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

Apply this formula for all numbers.

Step1:

LCM(805, 128) = 103040

GCD(805, 128) = ( 805 x 128 ) / 103040

= 805 / 128

= 805

Step2:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 805, 128, 908, 630 is 1
