Given numbers are 820, 997, 680

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

Apply this formula for all numbers.

Step1:

LCM(820, 997) = 817540

GCD(820, 997) = ( 820 x 997 ) / 817540

= 820 / 997

= 820

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 820, 997, 680 is 1
