Given numbers are 982, 986, 720, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(982, 986) = 484126
GCD(982, 986) = ( 982 x 986 ) / 484126
= 982 / 986
= 982
Step2:
LCM(2, 720) = 720
GCD(2, 720) = ( 2 x 720 ) / 720
= 2 / 720
= 2
Step3:
LCM(2, 815) = 1630
GCD(2, 815) = ( 2 x 815 ) / 1630
= 2 / 815
= 2
So, Greatest Common Divisor of 982, 986, 720, 815 is 1
