Given numbers are 785, 966, 393, 870

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 393 are 3 x 131

Prime factors of 870 are 2 x 3 x 5 x 29

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

Given numbers are 785, 966, 393, 870

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

Apply this formula for all numbers.

Step1:

LCM(785, 966) = 758310

GCD(785, 966) = ( 785 x 966 ) / 758310

= 785 / 966

= 785

Step2:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 785, 966, 393, 870 is 1
