The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 292 are 2 x 2 x 73

Prime factors of 406 are 2 x 7 x 29

Prime factors of 917 are 7 x 131

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

Given numbers are 685, 292, 406, 917

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

Apply this formula for all numbers.

Step1:

LCM(685, 292) = 200020

GCD(685, 292) = ( 685 x 292 ) / 200020

= 685 / 292

= 685

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 685, 292, 406, 917 is 1
