Given numbers are 820, 249, 786

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

Apply this formula for all numbers.

Step1:

LCM(820, 249) = 204180

GCD(820, 249) = ( 820 x 249 ) / 204180

= 820 / 249

= 820

Step2:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 820, 249, 786 is 1
