Given numbers are 722, 663, 646, 704

The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

Prime factors of 663 are 3 x 13 x 17

Prime factors of 646 are 2 x 17 x 19

Prime factors of 704 are 2 x 2 x 2 x 2 x 2 x 2 x 11

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

Given numbers are 722, 663, 646, 704

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

Apply this formula for all numbers.

Step1:

LCM(722, 663) = 478686

GCD(722, 663) = ( 722 x 663 ) / 478686

= 722 / 663

= 722

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 704) = 704

GCD(1, 704) = ( 1 x 704 ) / 704

= 1 / 704

= 1

So, Greatest Common Divisor of 722, 663, 646, 704 is 1
