Given numbers are 309, 464, 620, 662

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 464 are 2 x 2 x 2 x 2 x 29

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 662 are 2 x 331

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

Given numbers are 309, 464, 620, 662

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

Apply this formula for all numbers.

Step1:

LCM(309, 464) = 143376

GCD(309, 464) = ( 309 x 464 ) / 143376

= 309 / 464

= 309

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 309, 464, 620, 662 is 1
