Given numbers are 813, 327, 389, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 327) = 88617
GCD(813, 327) = ( 813 x 327 ) / 88617
= 813 / 327
= 813
Step2:
LCM(3, 389) = 1167
GCD(3, 389) = ( 3 x 389 ) / 1167
= 3 / 389
= 3
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 813, 327, 389, 561 is 1
