Given numbers are 504, 245, 165, 991

The list of prime factors of all numbers are

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 245 are 5 x 7 x 7

Prime factors of 165 are 3 x 5 x 11

Prime factors of 991 are 991

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

Given numbers are 504, 245, 165, 991

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

Apply this formula for all numbers.

Step1:

LCM(504, 245) = 17640

GCD(504, 245) = ( 504 x 245 ) / 17640

= 504 / 245

= 504

Step2:

LCM(7, 165) = 1155

GCD(7, 165) = ( 7 x 165 ) / 1155

= 7 / 165

= 7

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 504, 245, 165, 991 is 1
