Given numbers are 318, 988, 646, 247

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 646 are 2 x 17 x 19

Prime factors of 247 are 13 x 19

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

Given numbers are 318, 988, 646, 247

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

Apply this formula for all numbers.

Step1:

LCM(318, 988) = 157092

GCD(318, 988) = ( 318 x 988 ) / 157092

= 318 / 988

= 318

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

= 2 / 247

= 2

So, Greatest Common Divisor of 318, 988, 646, 247 is 1
