So the greatest common factor 51,428,397 is 1.
Lets's calculate LCM of 234,948,639
2 | 234, 948, 639 |
3 | 117, 474, 639 |
3 | 39, 158, 213 |
13, 158, 71 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 13 x 158 x 71 = 2625012
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2625012
Therefore, the GCF of Fractions 51/234,428/948,397/639 is 1/2625012
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 234,948,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(234,948,639) = 3
common factors(in case of two or more numbers have common factors) = 18
GCF(234,948,639) x common factors =3 x 18 = 54
LCM(234,948,639) = ( 234 × 948 × 639 ) / 54
LCM(234,948,639) = 141750648 / 54
LCM(234,948,639) = 2625012
