Given numbers are 665, 812, 187, 805

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

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

Prime factors of 187 are 11 x 17

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 665, 812, 187, 805

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

Apply this formula for all numbers.

Step1:

LCM(665, 812) = 77140

GCD(665, 812) = ( 665 x 812 ) / 77140

= 665 / 812

= 665

Step2:

LCM(7, 187) = 1309

GCD(7, 187) = ( 7 x 187 ) / 1309

= 7 / 187

= 7

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 665, 812, 187, 805 is 1
