Given numbers are 636, 647, 804, 817

The list of prime factors of all numbers are

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 647 are 647

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

Prime factors of 817 are 19 x 43

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

Given numbers are 636, 647, 804, 817

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

Apply this formula for all numbers.

Step1:

LCM(636, 647) = 411492

GCD(636, 647) = ( 636 x 647 ) / 411492

= 636 / 647

= 636

Step2:

LCM(1, 804) = 804

GCD(1, 804) = ( 1 x 804 ) / 804

= 1 / 804

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 636, 647, 804, 817 is 1
