Given numbers are 685, 146, 314, 638

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 146 are 2 x 73

Prime factors of 314 are 2 x 157

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 685, 146, 314, 638

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

Apply this formula for all numbers.

Step1:

LCM(685, 146) = 100010

GCD(685, 146) = ( 685 x 146 ) / 100010

= 685 / 146

= 685

Step2:

LCM(1, 314) = 314

GCD(1, 314) = ( 1 x 314 ) / 314

= 1 / 314

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 685, 146, 314, 638 is 1
