Given numbers are 391, 310, 133, 428

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 310 are 2 x 5 x 31

Prime factors of 133 are 7 x 19

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 391, 310, 133, 428

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

Apply this formula for all numbers.

Step1:

LCM(391, 310) = 121210

GCD(391, 310) = ( 391 x 310 ) / 121210

= 391 / 310

= 391

Step2:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 391, 310, 133, 428 is 1
