Given numbers are 781, 205, 308, 675

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 205 are 5 x 41

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

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

Given numbers are 781, 205, 308, 675

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

Apply this formula for all numbers.

Step1:

LCM(781, 205) = 160105

GCD(781, 205) = ( 781 x 205 ) / 160105

= 781 / 205

= 781

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 675) = 675

GCD(1, 675) = ( 1 x 675 ) / 675

= 1 / 675

= 1

So, Greatest Common Divisor of 781, 205, 308, 675 is 1
