Given numbers are 724, 391, 484, 756

The list of prime factors of all numbers are

Prime factors of 724 are 2 x 2 x 181

Prime factors of 391 are 17 x 23

Prime factors of 484 are 2 x 2 x 11 x 11

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 724, 391, 484, 756

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

Apply this formula for all numbers.

Step1:

LCM(724, 391) = 283084

GCD(724, 391) = ( 724 x 391 ) / 283084

= 724 / 391

= 724

Step2:

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

= 1 / 484

= 1

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 724, 391, 484, 756 is 1
