Given numbers are 806, 980, 90

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

Apply this formula for all numbers.

Step1:

LCM(806, 980) = 394940

GCD(806, 980) = ( 806 x 980 ) / 394940

= 806 / 980

= 806

Step2:

LCM(2, 90) = 90

GCD(2, 90) = ( 2 x 90 ) / 90

= 2 / 90

= 2

So, Greatest Common Divisor of 806, 980, 90 is 2
