Given numbers are 805, 813, 221, 867

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 813 are 3 x 271

Prime factors of 221 are 13 x 17

Prime factors of 867 are 3 x 17 x 17

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

Given numbers are 805, 813, 221, 867

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

Apply this formula for all numbers.

Step1:

LCM(805, 813) = 654465

GCD(805, 813) = ( 805 x 813 ) / 654465

= 805 / 813

= 805

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 867) = 867

GCD(1, 867) = ( 1 x 867 ) / 867

= 1 / 867

= 1

So, Greatest Common Divisor of 805, 813, 221, 867 is 1
