Given numbers are 342, 254, 120, 245

The list of prime factors of all numbers are

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 254 are 2 x 127

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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 342, 254, 120, 245

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

Apply this formula for all numbers.

Step1:

LCM(342, 254) = 43434

GCD(342, 254) = ( 342 x 254 ) / 43434

= 342 / 254

= 342

Step2:

LCM(2, 120) = 120

GCD(2, 120) = ( 2 x 120 ) / 120

= 2 / 120

= 2

Step3:

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

= 2 / 245

= 2

So, Greatest Common Divisor of 342, 254, 120, 245 is 1
