Given numbers are 245, 905, 912, 425

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 905 are 5 x 181

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 425 are 5 x 5 x 17

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

Given numbers are 245, 905, 912, 425

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

Apply this formula for all numbers.

Step1:

LCM(245, 905) = 44345

GCD(245, 905) = ( 245 x 905 ) / 44345

= 245 / 905

= 245

Step2:

LCM(5, 912) = 4560

GCD(5, 912) = ( 5 x 912 ) / 4560

= 5 / 912

= 5

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 245, 905, 912, 425 is 1
