The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 454 are 2 x 227

Prime factors of 746 are 2 x 373

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

Given numbers are 561, 686, 454, 746

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

Apply this formula for all numbers.

Step1:

LCM(561, 686) = 384846

GCD(561, 686) = ( 561 x 686 ) / 384846

= 561 / 686

= 561

Step2:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

Step3:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

So, Greatest Common Divisor of 561, 686, 454, 746 is 1
