Given numbers are 245, 165, 485, 798

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 165 are 3 x 5 x 11

Prime factors of 485 are 5 x 97

Prime factors of 798 are 2 x 3 x 7 x 19

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

Given numbers are 245, 165, 485, 798

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

Apply this formula for all numbers.

Step1:

LCM(245, 165) = 8085

GCD(245, 165) = ( 245 x 165 ) / 8085

= 245 / 165

= 245

Step2:

LCM(5, 485) = 485

GCD(5, 485) = ( 5 x 485 ) / 485

= 5 / 485

= 5

Step3:

LCM(5, 798) = 3990

GCD(5, 798) = ( 5 x 798 ) / 3990

= 5 / 798

= 5

So, Greatest Common Divisor of 245, 165, 485, 798 is 1
