Given numbers are 609, 660, 563, 398

The list of prime factors of all numbers are

Prime factors of 609 are 3 x 7 x 29

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 563 are 563

Prime factors of 398 are 2 x 199

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

Given numbers are 609, 660, 563, 398

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

Apply this formula for all numbers.

Step1:

LCM(609, 660) = 133980

GCD(609, 660) = ( 609 x 660 ) / 133980

= 609 / 660

= 609

Step2:

LCM(3, 563) = 1689

GCD(3, 563) = ( 3 x 563 ) / 1689

= 3 / 563

= 3

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 609, 660, 563, 398 is 1
