Given numbers are 650, 609, 660, 789

The list of prime factors of all numbers are

Prime factors of 650 are 2 x 5 x 5 x 13

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 789 are 3 x 263

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

Given numbers are 650, 609, 660, 789

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

Apply this formula for all numbers.

Step1:

LCM(650, 609) = 395850

GCD(650, 609) = ( 650 x 609 ) / 395850

= 650 / 609

= 650

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 650, 609, 660, 789 is 1
