Given numbers are 561, 659, 621, 744

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 659 are 659

Prime factors of 621 are 3 x 3 x 3 x 23

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

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

Given numbers are 561, 659, 621, 744

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

Apply this formula for all numbers.

Step1:

LCM(561, 659) = 369699

GCD(561, 659) = ( 561 x 659 ) / 369699

= 561 / 659

= 561

Step2:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

Step3:

LCM(1, 744) = 744

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

= 1 / 744

= 1

So, Greatest Common Divisor of 561, 659, 621, 744 is 1
