Given numbers are 406, 138, 259, 245

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 138 are 2 x 3 x 23

Prime factors of 259 are 7 x 37

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 406, 138, 259, 245

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

Apply this formula for all numbers.

Step1:

LCM(406, 138) = 28014

GCD(406, 138) = ( 406 x 138 ) / 28014

= 406 / 138

= 406

Step2:

LCM(2, 259) = 518

GCD(2, 259) = ( 2 x 259 ) / 518

= 2 / 259

= 2

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 406, 138, 259, 245 is 1
