Given numbers are 810, 789, 516, 540

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

Apply this formula for all numbers.

Step1:

LCM(810, 789) = 213030

GCD(810, 789) = ( 810 x 789 ) / 213030

= 810 / 789

= 810

Step2:

LCM(3, 516) = 516

GCD(3, 516) = ( 3 x 516 ) / 516

= 3 / 516

= 3

Step3:

LCM(3, 540) = 540

GCD(3, 540) = ( 3 x 540 ) / 540

= 3 / 540

= 3

So, Greatest Common Divisor of 810, 789, 516, 540 is 3
