Given numbers are 399, 894, 815, 777

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

Apply this formula for all numbers.

Step1:

LCM(399, 894) = 118902

GCD(399, 894) = ( 399 x 894 ) / 118902

= 399 / 894

= 399

Step2:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 399, 894, 815, 777 is 1
