Given numbers are 989, 979, 415, 517
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 979) = 968231
GCD(989, 979) = ( 989 x 979 ) / 968231
= 989 / 979
= 989
Step2:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
Step3:
LCM(1, 517) = 517
GCD(1, 517) = ( 1 x 517 ) / 517
= 1 / 517
= 1
So, Greatest Common Divisor of 989, 979, 415, 517 is 1
