Given numbers are 831, 210, 683, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 210) = 58170
GCD(831, 210) = ( 831 x 210 ) / 58170
= 831 / 210
= 831
Step2:
LCM(3, 683) = 2049
GCD(3, 683) = ( 3 x 683 ) / 2049
= 3 / 683
= 3
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 831, 210, 683, 865 is 1
