Given numbers are 406, 218, 818, 561

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 218 are 2 x 109

Prime factors of 818 are 2 x 409

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 406, 218, 818, 561

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

Apply this formula for all numbers.

Step1:

LCM(406, 218) = 44254

GCD(406, 218) = ( 406 x 218 ) / 44254

= 406 / 218

= 406

Step2:

LCM(2, 818) = 818

GCD(2, 818) = ( 2 x 818 ) / 818

= 2 / 818

= 2

Step3:

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

= 2 / 561

= 2

So, Greatest Common Divisor of 406, 218, 818, 561 is 1
