Given numbers are 115, 986, 405, 868
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 986) = 113390
GCD(115, 986) = ( 115 x 986 ) / 113390
= 115 / 986
= 115
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
Step3:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
So, Greatest Common Divisor of 115, 986, 405, 868 is 1
