Given numbers are 851, 839, 820

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

Apply this formula for all numbers.

Step1:

LCM(851, 839) = 713989

GCD(851, 839) = ( 851 x 839 ) / 713989

= 851 / 839

= 851

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 851, 839, 820 is 1
