Given numbers are 830, 391, 663, 960

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 391 are 17 x 23

Prime factors of 663 are 3 x 13 x 17

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 830, 391, 663, 960

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

Apply this formula for all numbers.

Step1:

LCM(830, 391) = 324530

GCD(830, 391) = ( 830 x 391 ) / 324530

= 830 / 391

= 830

Step2:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

Step3:

LCM(1, 960) = 960

GCD(1, 960) = ( 1 x 960 ) / 960

= 1 / 960

= 1

So, Greatest Common Divisor of 830, 391, 663, 960 is 1
