Given numbers are 561, 810, 383, 664

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 383 are 383

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 561, 810, 383, 664

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

Apply this formula for all numbers.

Step1:

LCM(561, 810) = 151470

GCD(561, 810) = ( 561 x 810 ) / 151470

= 561 / 810

= 561

Step2:

LCM(3, 383) = 1149

GCD(3, 383) = ( 3 x 383 ) / 1149

= 3 / 383

= 3

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 561, 810, 383, 664 is 1
