Given numbers are 985, 717, 620, 510

The list of prime factors of all numbers are

Prime factors of 985 are 5 x 197

Prime factors of 717 are 3 x 239

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

Prime factors of 510 are 2 x 3 x 5 x 17

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

Given numbers are 985, 717, 620, 510

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

Apply this formula for all numbers.

Step1:

LCM(985, 717) = 706245

GCD(985, 717) = ( 985 x 717 ) / 706245

= 985 / 717

= 985

Step2:

LCM(1, 620) = 620

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

= 1 / 620

= 1

Step3:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

So, Greatest Common Divisor of 985, 717, 620, 510 is 1
