Given numbers are 195, 130, 457, 240

The list of prime factors of all numbers are

Prime factors of 195 are 3 x 5 x 13

Prime factors of 130 are 2 x 5 x 13

Prime factors of 457 are 457

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 195, 130, 457, 240

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

Apply this formula for all numbers.

Step1:

LCM(195, 130) = 390

GCD(195, 130) = ( 195 x 130 ) / 390

= 195 / 130

= 195

Step2:

LCM(65, 457) = 29705

GCD(65, 457) = ( 65 x 457 ) / 29705

= 65 / 457

= 65

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 195, 130, 457, 240 is 1
