Given numbers are 561, 168, 330, 830

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 830 are 2 x 5 x 83

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

Given numbers are 561, 168, 330, 830

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

Apply this formula for all numbers.

Step1:

LCM(561, 168) = 31416

GCD(561, 168) = ( 561 x 168 ) / 31416

= 561 / 168

= 561

Step2:

LCM(3, 330) = 330

GCD(3, 330) = ( 3 x 330 ) / 330

= 3 / 330

= 3

Step3:

LCM(3, 830) = 2490

GCD(3, 830) = ( 3 x 830 ) / 2490

= 3 / 830

= 3

So, Greatest Common Divisor of 561, 168, 330, 830 is 1
