Given numbers are 245, 406, 438, 425

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 438 are 2 x 3 x 73

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, 406, 438, 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, 406) = 14210

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

= 245 / 406

= 245

Step2:

LCM(7, 438) = 3066

GCD(7, 438) = ( 7 x 438 ) / 3066

= 7 / 438

= 7

Step3:

LCM(1, 425) = 425

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

= 1 / 425

= 1

So, Greatest Common Divisor of 245, 406, 438, 425 is 1
