Given numbers are 813, 400, 699, 431

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 699 are 3 x 233

Prime factors of 431 are 431

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

Given numbers are 813, 400, 699, 431

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

Apply this formula for all numbers.

Step1:

LCM(813, 400) = 325200

GCD(813, 400) = ( 813 x 400 ) / 325200

= 813 / 400

= 813

Step2:

LCM(1, 699) = 699

GCD(1, 699) = ( 1 x 699 ) / 699

= 1 / 699

= 1

Step3:

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

= 1 / 431

= 1

So, Greatest Common Divisor of 813, 400, 699, 431 is 1
