Given numbers are 645, 843, 86, 800

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 843 are 3 x 281

Prime factors of 86 are 2 x 43

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 645, 843, 86, 800

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

Apply this formula for all numbers.

Step1:

LCM(645, 843) = 181245

GCD(645, 843) = ( 645 x 843 ) / 181245

= 645 / 843

= 645

Step2:

LCM(3, 86) = 258

GCD(3, 86) = ( 3 x 86 ) / 258

= 3 / 86

= 3

Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

So, Greatest Common Divisor of 645, 843, 86, 800 is 1
