Given numbers are 815, 842, 808, 711

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

Apply this formula for all numbers.

Step1:

LCM(815, 842) = 686230

GCD(815, 842) = ( 815 x 842 ) / 686230

= 815 / 842

= 815

Step2:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

Step3:

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

= 1 / 711

= 1

So, Greatest Common Divisor of 815, 842, 808, 711 is 1
