Given numbers are 685, 897, 345, 881

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

Apply this formula for all numbers.

Step1:

LCM(685, 897) = 614445

GCD(685, 897) = ( 685 x 897 ) / 614445

= 685 / 897

= 685

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

So, Greatest Common Divisor of 685, 897, 345, 881 is 1
