Given numbers are 685, 775, 897, 904

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

Apply this formula for all numbers.

Step1:

LCM(685, 775) = 106175

GCD(685, 775) = ( 685 x 775 ) / 106175

= 685 / 775

= 685

Step2:

LCM(5, 897) = 4485

GCD(5, 897) = ( 5 x 897 ) / 4485

= 5 / 897

= 5

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 685, 775, 897, 904 is 1
