Given numbers are 820, 166, 397

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

Apply this formula for all numbers.

Step1:

LCM(820, 166) = 68060

GCD(820, 166) = ( 820 x 166 ) / 68060

= 820 / 166

= 820

Step2:

LCM(2, 397) = 794

GCD(2, 397) = ( 2 x 397 ) / 794

= 2 / 397

= 2

So, Greatest Common Divisor of 820, 166, 397 is 1
