Given numbers are 843, 718, 856, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(843, 718) = 605274
GCD(843, 718) = ( 843 x 718 ) / 605274
= 843 / 718
= 843
Step2:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 843, 718, 856, 991 is 1
