Greatest Common Factor
We found the factors 75,686,292 . The biggest common factor number is the GCF number.
So the greatest common factor 75,686,292 is 1.
Lets's calculate LCM of 30,51,759
3 | 30, 51, 759 |
10, 17, 253 |
∴ So the LCM of the given numbers is 3 x 10 x 17 x 253 = 129030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/129030
Therefore, the GCF of Fractions 75/30,686/51,292/759 is 1/129030
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 30,51,759 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,51,759) = 3
common factors(in case of two or more numbers have common factors) = 3
GCF(30,51,759) x common factors =3 x 3 = 9
LCM(30,51,759) = ( 30 × 51 × 759 ) / 9
LCM(30,51,759) = 1161270 / 9
LCM(30,51,759) = 129030
