Given numbers are 145, 930, 561, 609

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 561 are 3 x 11 x 17

Prime factors of 609 are 3 x 7 x 29

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

Given numbers are 145, 930, 561, 609

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

Apply this formula for all numbers.

Step1:

LCM(145, 930) = 26970

GCD(145, 930) = ( 145 x 930 ) / 26970

= 145 / 930

= 145

Step2:

LCM(5, 561) = 2805

GCD(5, 561) = ( 5 x 561 ) / 2805

= 5 / 561

= 5

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 145, 930, 561, 609 is 1
