Given numbers are 809, 305, 891, 835
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 305) = 246745
GCD(809, 305) = ( 809 x 305 ) / 246745
= 809 / 305
= 809
Step2:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
Step3:
LCM(1, 835) = 835
GCD(1, 835) = ( 1 x 835 ) / 835
= 1 / 835
= 1
So, Greatest Common Divisor of 809, 305, 891, 835 is 1
