Given numbers are 855, 735, 905, 646

The list of prime factors of all numbers are

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

Prime factors of 735 are 3 x 5 x 7 x 7

Prime factors of 905 are 5 x 181

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 855, 735, 905, 646

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

Apply this formula for all numbers.

Step1:

LCM(855, 735) = 41895

GCD(855, 735) = ( 855 x 735 ) / 41895

= 855 / 735

= 855

Step2:

LCM(15, 905) = 2715

GCD(15, 905) = ( 15 x 905 ) / 2715

= 15 / 905

= 15

Step3:

LCM(5, 646) = 3230

GCD(5, 646) = ( 5 x 646 ) / 3230

= 5 / 646

= 5

So, Greatest Common Divisor of 855, 735, 905, 646 is 1
