Given numbers are 245, 663, 272, 928

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 663 are 3 x 13 x 17

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

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

Given numbers are 245, 663, 272, 928

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

Apply this formula for all numbers.

Step1:

LCM(245, 663) = 162435

GCD(245, 663) = ( 245 x 663 ) / 162435

= 245 / 663

= 245

Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

Step3:

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

= 1 / 928

= 1

So, Greatest Common Divisor of 245, 663, 272, 928 is 1
