Given numbers are 401, 810, 806, 690

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 806 are 2 x 13 x 31

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 401, 810, 806, 690

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

Apply this formula for all numbers.

Step1:

LCM(401, 810) = 324810

GCD(401, 810) = ( 401 x 810 ) / 324810

= 401 / 810

= 401

Step2:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 401, 810, 806, 690 is 1
