Given numbers are 693, 520, 491, 963

The list of prime factors of all numbers are

Prime factors of 693 are 3 x 3 x 7 x 11

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

Prime factors of 491 are 491

Prime factors of 963 are 3 x 3 x 107

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

Given numbers are 693, 520, 491, 963

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

Apply this formula for all numbers.

Step1:

LCM(693, 520) = 360360

GCD(693, 520) = ( 693 x 520 ) / 360360

= 693 / 520

= 693

Step2:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

Step3:

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

= 1 / 963

= 1

So, Greatest Common Divisor of 693, 520, 491, 963 is 1
