Given numbers are 689, 303, 820

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

Apply this formula for all numbers.

Step1:

LCM(689, 303) = 208767

GCD(689, 303) = ( 689 x 303 ) / 208767

= 689 / 303

= 689

Step2:

LCM(1, 820) = 820

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

= 1 / 820

= 1

So, Greatest Common Divisor of 689, 303, 820 is 1
