Given numbers are 904, 642, 855, 635

The list of prime factors of all numbers are

Prime factors of 904 are 2 x 2 x 2 x 113

Prime factors of 642 are 2 x 3 x 107

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 635 are 5 x 127

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

Given numbers are 904, 642, 855, 635

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

Apply this formula for all numbers.

Step1:

LCM(904, 642) = 290184

GCD(904, 642) = ( 904 x 642 ) / 290184

= 904 / 642

= 904

Step2:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 904, 642, 855, 635 is 1
