Given numbers are 310, 628, 758, 781

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 628 are 2 x 2 x 157

Prime factors of 758 are 2 x 379

Prime factors of 781 are 11 x 71

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

Given numbers are 310, 628, 758, 781

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

Apply this formula for all numbers.

Step1:

LCM(310, 628) = 97340

GCD(310, 628) = ( 310 x 628 ) / 97340

= 310 / 628

= 310

Step2:

LCM(2, 758) = 758

GCD(2, 758) = ( 2 x 758 ) / 758

= 2 / 758

= 2

Step3:

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

= 2 / 781

= 2

So, Greatest Common Divisor of 310, 628, 758, 781 is 1
