Given numbers are 647, 654, 865, 564

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 654 are 2 x 3 x 109

Prime factors of 865 are 5 x 173

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

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

Given numbers are 647, 654, 865, 564

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

Apply this formula for all numbers.

Step1:

LCM(647, 654) = 423138

GCD(647, 654) = ( 647 x 654 ) / 423138

= 647 / 654

= 647

Step2:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

Step3:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

So, Greatest Common Divisor of 647, 654, 865, 564 is 1
