Given numbers are 394, 818, 800, 861

The list of prime factors of all numbers are

Prime factors of 394 are 2 x 197

Prime factors of 818 are 2 x 409

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 394, 818, 800, 861

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

Apply this formula for all numbers.

Step1:

LCM(394, 818) = 161146

GCD(394, 818) = ( 394 x 818 ) / 161146

= 394 / 818

= 394

Step2:

LCM(2, 800) = 800

GCD(2, 800) = ( 2 x 800 ) / 800

= 2 / 800

= 2

Step3:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

So, Greatest Common Divisor of 394, 818, 800, 861 is 1
