Given numbers are 647, 564, 794, 810

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 794 are 2 x 397

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 647, 564, 794, 810

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

Apply this formula for all numbers.

Step1:

LCM(647, 564) = 364908

GCD(647, 564) = ( 647 x 564 ) / 364908

= 647 / 564

= 647

Step2:

LCM(1, 794) = 794

GCD(1, 794) = ( 1 x 794 ) / 794

= 1 / 794

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 647, 564, 794, 810 is 1
