Given numbers are 805, 364, 812, 663

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 805, 364, 812, 663

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

Apply this formula for all numbers.

Step1:

LCM(805, 364) = 41860

GCD(805, 364) = ( 805 x 364 ) / 41860

= 805 / 364

= 805

Step2:

LCM(7, 812) = 812

GCD(7, 812) = ( 7 x 812 ) / 812

= 7 / 812

= 7

Step3:

LCM(7, 663) = 4641

GCD(7, 663) = ( 7 x 663 ) / 4641

= 7 / 663

= 7

So, Greatest Common Divisor of 805, 364, 812, 663 is 1
