Given numbers are 813, 785, 76, 556

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

Apply this formula for all numbers.

Step1:

LCM(813, 785) = 638205

GCD(813, 785) = ( 813 x 785 ) / 638205

= 813 / 785

= 813

Step2:

LCM(1, 76) = 76

GCD(1, 76) = ( 1 x 76 ) / 76

= 1 / 76

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 813, 785, 76, 556 is 1
