Given numbers are 686, 970, 730, 311

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 970 are 2 x 5 x 97

Prime factors of 730 are 2 x 5 x 73

Prime factors of 311 are 311

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

Given numbers are 686, 970, 730, 311

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

Apply this formula for all numbers.

Step1:

LCM(686, 970) = 332710

GCD(686, 970) = ( 686 x 970 ) / 332710

= 686 / 970

= 686

Step2:

LCM(2, 730) = 730

GCD(2, 730) = ( 2 x 730 ) / 730

= 2 / 730

= 2

Step3:

LCM(2, 311) = 622

GCD(2, 311) = ( 2 x 311 ) / 622

= 2 / 311

= 2

So, Greatest Common Divisor of 686, 970, 730, 311 is 1
