Given numbers are 855, 245, 361, 851

The list of prime factors of all numbers are

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

Prime factors of 245 are 5 x 7 x 7

Prime factors of 361 are 19 x 19

Prime factors of 851 are 23 x 37

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

Given numbers are 855, 245, 361, 851

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

Apply this formula for all numbers.

Step1:

LCM(855, 245) = 41895

GCD(855, 245) = ( 855 x 245 ) / 41895

= 855 / 245

= 855

Step2:

LCM(5, 361) = 1805

GCD(5, 361) = ( 5 x 361 ) / 1805

= 5 / 361

= 5

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 855, 245, 361, 851 is 1
