Given numbers are 403, 105, 424, 680

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 105 are 3 x 5 x 7

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 403, 105, 424, 680

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

Apply this formula for all numbers.

Step1:

LCM(403, 105) = 42315

GCD(403, 105) = ( 403 x 105 ) / 42315

= 403 / 105

= 403

Step2:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 403, 105, 424, 680 is 1
