Given numbers are 774, 324, 255, 245

The list of prime factors of all numbers are

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 255 are 3 x 5 x 17

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 774, 324, 255, 245

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

Apply this formula for all numbers.

Step1:

LCM(774, 324) = 13932

GCD(774, 324) = ( 774 x 324 ) / 13932

= 774 / 324

= 774

Step2:

LCM(18, 255) = 1530

GCD(18, 255) = ( 18 x 255 ) / 1530

= 18 / 255

= 18

Step3:

LCM(3, 245) = 735

GCD(3, 245) = ( 3 x 245 ) / 735

= 3 / 245

= 3

So, Greatest Common Divisor of 774, 324, 255, 245 is 1
