Given numbers are 663, 856, 744, 697

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 697 are 17 x 41

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

Given numbers are 663, 856, 744, 697

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

Apply this formula for all numbers.

Step1:

LCM(663, 856) = 567528

GCD(663, 856) = ( 663 x 856 ) / 567528

= 663 / 856

= 663

Step2:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

Step3:

LCM(1, 697) = 697

GCD(1, 697) = ( 1 x 697 ) / 697

= 1 / 697

= 1

So, Greatest Common Divisor of 663, 856, 744, 697 is 1
