Given numbers are 685, 665, 784, 190

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 665 are 5 x 7 x 19

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 190 are 2 x 5 x 19

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

Given numbers are 685, 665, 784, 190

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

Apply this formula for all numbers.

Step1:

LCM(685, 665) = 91105

GCD(685, 665) = ( 685 x 665 ) / 91105

= 685 / 665

= 685

Step2:

LCM(5, 784) = 3920

GCD(5, 784) = ( 5 x 784 ) / 3920

= 5 / 784

= 5

Step3:

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

= 1 / 190

= 1

So, Greatest Common Divisor of 685, 665, 784, 190 is 1
