Given numbers are 210, 654, 561, 814

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 654 are 2 x 3 x 109

Prime factors of 561 are 3 x 11 x 17

Prime factors of 814 are 2 x 11 x 37

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

Given numbers are 210, 654, 561, 814

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

Apply this formula for all numbers.

Step1:

LCM(210, 654) = 22890

GCD(210, 654) = ( 210 x 654 ) / 22890

= 210 / 654

= 210

Step2:

LCM(6, 561) = 1122

GCD(6, 561) = ( 6 x 561 ) / 1122

= 6 / 561

= 6

Step3:

LCM(3, 814) = 2442

GCD(3, 814) = ( 3 x 814 ) / 2442

= 3 / 814

= 3

So, Greatest Common Divisor of 210, 654, 561, 814 is 1
