Greatest Common Factor
We found the factors 65,38,986 . The biggest common factor number is the GCF number.
So the greatest common factor 65,38,986 is 1.
Lets's calculate LCM of 51,123,747
3 | 51, 123, 747 |
17, 41, 249 |
∴ So the LCM of the given numbers is 3 x 17 x 41 x 249 = 520659
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/520659
Therefore, the GCF of Fractions 65/51,38/123,986/747 is 1/520659
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 51,123,747 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,123,747) = 3
common factors(in case of two or more numbers have common factors) = 3
GCF(51,123,747) x common factors =3 x 3 = 9
LCM(51,123,747) = ( 51 × 123 × 747 ) / 9
LCM(51,123,747) = 4685931 / 9
LCM(51,123,747) = 520659
