Given numbers are 685, 408, 515, 899

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

Apply this formula for all numbers.

Step1:

LCM(685, 408) = 279480

GCD(685, 408) = ( 685 x 408 ) / 279480

= 685 / 408

= 685

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

Step3:

LCM(1, 899) = 899

GCD(1, 899) = ( 1 x 899 ) / 899

= 1 / 899

= 1

So, Greatest Common Divisor of 685, 408, 515, 899 is 1
