Given numbers are 245, 321, 407, 254

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 321 are 3 x 107

Prime factors of 407 are 11 x 37

Prime factors of 254 are 2 x 127

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

Given numbers are 245, 321, 407, 254

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

Apply this formula for all numbers.

Step1:

LCM(245, 321) = 78645

GCD(245, 321) = ( 245 x 321 ) / 78645

= 245 / 321

= 245

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 245, 321, 407, 254 is 1
