Given numbers are 314, 665, 655, 398

The list of prime factors of all numbers are

Prime factors of 314 are 2 x 157

Prime factors of 665 are 5 x 7 x 19

Prime factors of 655 are 5 x 131

Prime factors of 398 are 2 x 199

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

Given numbers are 314, 665, 655, 398

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

Apply this formula for all numbers.

Step1:

LCM(314, 665) = 208810

GCD(314, 665) = ( 314 x 665 ) / 208810

= 314 / 665

= 314

Step2:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 314, 665, 655, 398 is 1
