Given numbers are 609, 800, 865, 649

The list of prime factors of all numbers are

Prime factors of 609 are 3 x 7 x 29

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

Prime factors of 865 are 5 x 173

Prime factors of 649 are 11 x 59

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

Given numbers are 609, 800, 865, 649

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

Apply this formula for all numbers.

Step1:

LCM(609, 800) = 487200

GCD(609, 800) = ( 609 x 800 ) / 487200

= 609 / 800

= 609

Step2:

LCM(1, 865) = 865

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

= 1 / 865

= 1

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 609, 800, 865, 649 is 1
