Given numbers are 561, 320, 446, 426

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 446 are 2 x 223

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 561, 320, 446, 426

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

Apply this formula for all numbers.

Step1:

LCM(561, 320) = 179520

GCD(561, 320) = ( 561 x 320 ) / 179520

= 561 / 320

= 561

Step2:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 561, 320, 446, 426 is 1
