Given numbers are 645, 804, 423, 418

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 804 are 2 x 2 x 3 x 67

Prime factors of 423 are 3 x 3 x 47

Prime factors of 418 are 2 x 11 x 19

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

Given numbers are 645, 804, 423, 418

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

Apply this formula for all numbers.

Step1:

LCM(645, 804) = 172860

GCD(645, 804) = ( 645 x 804 ) / 172860

= 645 / 804

= 645

Step2:

LCM(3, 423) = 423

GCD(3, 423) = ( 3 x 423 ) / 423

= 3 / 423

= 3

Step3:

LCM(3, 418) = 1254

GCD(3, 418) = ( 3 x 418 ) / 1254

= 3 / 418

= 3

So, Greatest Common Divisor of 645, 804, 423, 418 is 1
