Given numbers are 315, 410, 646, 855

The list of prime factors of all numbers are

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 410 are 2 x 5 x 41

Prime factors of 646 are 2 x 17 x 19

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

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

Given numbers are 315, 410, 646, 855

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

Apply this formula for all numbers.

Step1:

LCM(315, 410) = 25830

GCD(315, 410) = ( 315 x 410 ) / 25830

= 315 / 410

= 315

Step2:

LCM(5, 646) = 3230

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

= 5 / 646

= 5

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 315, 410, 646, 855 is 1
