Given numbers are 785, 861, 350, 520

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 861 are 3 x 7 x 41

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 785, 861, 350, 520

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

Apply this formula for all numbers.

Step1:

LCM(785, 861) = 675885

GCD(785, 861) = ( 785 x 861 ) / 675885

= 785 / 861

= 785

Step2:

LCM(1, 350) = 350

GCD(1, 350) = ( 1 x 350 ) / 350

= 1 / 350

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 785, 861, 350, 520 is 1
