Given numbers are 905, 855, 769, 437

The list of prime factors of all numbers are

Prime factors of 905 are 5 x 181

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

Prime factors of 769 are 769

Prime factors of 437 are 19 x 23

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

Given numbers are 905, 855, 769, 437

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

Apply this formula for all numbers.

Step1:

LCM(905, 855) = 154755

GCD(905, 855) = ( 905 x 855 ) / 154755

= 905 / 855

= 905

Step2:

LCM(5, 769) = 3845

GCD(5, 769) = ( 5 x 769 ) / 3845

= 5 / 769

= 5

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 905, 855, 769, 437 is 1
