Given numbers are 245, 406, 520, 228

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 406 are 2 x 7 x 29

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 228 are 2 x 2 x 3 x 19

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

Given numbers are 245, 406, 520, 228

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

Apply this formula for all numbers.

Step1:

LCM(245, 406) = 14210

GCD(245, 406) = ( 245 x 406 ) / 14210

= 245 / 406

= 245

Step2:

LCM(7, 520) = 3640

GCD(7, 520) = ( 7 x 520 ) / 3640

= 7 / 520

= 7

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 245, 406, 520, 228 is 1
