Given numbers are 634, 392, 906, 765

The list of prime factors of all numbers are

Prime factors of 634 are 2 x 317

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 906 are 2 x 3 x 151

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 634, 392, 906, 765

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

Apply this formula for all numbers.

Step1:

LCM(634, 392) = 124264

GCD(634, 392) = ( 634 x 392 ) / 124264

= 634 / 392

= 634

Step2:

LCM(2, 906) = 906

GCD(2, 906) = ( 2 x 906 ) / 906

= 2 / 906

= 2

Step3:

LCM(2, 765) = 1530

GCD(2, 765) = ( 2 x 765 ) / 1530

= 2 / 765

= 2

So, Greatest Common Divisor of 634, 392, 906, 765 is 1
