Given numbers are 815, 711, 208

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

Apply this formula for all numbers.

Step1:

LCM(815, 711) = 579465

GCD(815, 711) = ( 815 x 711 ) / 579465

= 815 / 711

= 815

Step2:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 815, 711, 208 is 1
