Given numbers are 730, 823, 858, 891
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(730, 823) = 600790
GCD(730, 823) = ( 730 x 823 ) / 600790
= 730 / 823
= 730
Step2:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 730, 823, 858, 891 is 1
