Greatest Common Factor
We found the factors 30,12,759 . The biggest common factor number is the GCF number.
So the greatest common factor 30,12,759 is 3.
Lets's calculate LCM of 76,122,481
2 | 76, 122, 481 |
38, 61, 481 |
∴ So the LCM of the given numbers is 2 x 38 x 61 x 481 = 2229916
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2229916
Therefore, the GCF of Fractions 30/76,12/122,759/481 is 3/2229916
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 76,122,481 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,122,481) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(76,122,481) x common factors =1 x 2 = 2
LCM(76,122,481) = ( 76 × 122 × 481 ) / 2
LCM(76,122,481) = 4459832 / 2
LCM(76,122,481) = 2229916
