Given numbers are 609, 720, 349, 655

The list of prime factors of all numbers are

Prime factors of 609 are 3 x 7 x 29

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 349 are 349

Prime factors of 655 are 5 x 131

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

Given numbers are 609, 720, 349, 655

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

Apply this formula for all numbers.

Step1:

LCM(609, 720) = 146160

GCD(609, 720) = ( 609 x 720 ) / 146160

= 609 / 720

= 609

Step2:

LCM(3, 349) = 1047

GCD(3, 349) = ( 3 x 349 ) / 1047

= 3 / 349

= 3

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 609, 720, 349, 655 is 1
