Greatest Common Factor
We found the factors 25,78,145 . The biggest common factor number is the GCF number.
So the greatest common factor 25,78,145 is 1.
Lets's calculate LCM of 78,206,721
2 | 78, 206, 721 |
103 | 39, 103, 721 |
39, 1, 7 |
∴ So the LCM of the given numbers is 2 x 103 x 39 x 1 x 7 = 56238
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/56238
Therefore, the GCF of Fractions 25/78,78/206,145/721 is 1/56238
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 78,206,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,206,721) = 1
common factors(in case of two or more numbers have common factors) = 206
GCF(78,206,721) x common factors =1 x 206 = 206
LCM(78,206,721) = ( 78 × 206 × 721 ) / 206
LCM(78,206,721) = 11585028 / 206
LCM(78,206,721) = 56238
