Given numbers are 609, 550, 865, 280

The list of prime factors of all numbers are

Prime factors of 609 are 3 x 7 x 29

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 865 are 5 x 173

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 609, 550, 865, 280

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

Apply this formula for all numbers.

Step1:

LCM(609, 550) = 334950

GCD(609, 550) = ( 609 x 550 ) / 334950

= 609 / 550

= 609

Step2:

LCM(1, 865) = 865

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

= 1 / 865

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 609, 550, 865, 280 is 1
