The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 407 are 11 x 37

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 119 are 7 x 17

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

Given numbers are 685, 407, 690, 119

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

Apply this formula for all numbers.

Step1:

LCM(685, 407) = 278795

GCD(685, 407) = ( 685 x 407 ) / 278795

= 685 / 407

= 685

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 119) = 119

GCD(1, 119) = ( 1 x 119 ) / 119

= 1 / 119

= 1

So, Greatest Common Divisor of 685, 407, 690, 119 is 1
