Given numbers are 685, 401, 78, 588

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 401 are 401

Prime factors of 78 are 2 x 3 x 13

Prime factors of 588 are 2 x 2 x 3 x 7 x 7

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

Given numbers are 685, 401, 78, 588

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

Apply this formula for all numbers.

Step1:

LCM(685, 401) = 274685

GCD(685, 401) = ( 685 x 401 ) / 274685

= 685 / 401

= 685

Step2:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

Step3:

LCM(1, 588) = 588

GCD(1, 588) = ( 1 x 588 ) / 588

= 1 / 588

= 1

So, Greatest Common Divisor of 685, 401, 78, 588 is 1
