Given numbers are 191, 856, 183, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(191, 856) = 163496
GCD(191, 856) = ( 191 x 856 ) / 163496
= 191 / 856
= 191
Step2:
LCM(1, 183) = 183
GCD(1, 183) = ( 1 x 183 ) / 183
= 1 / 183
= 1
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 191, 856, 183, 686 is 1
