So the greatest common factor 58,878,168 is 2.
Lets's calculate LCM of 78,39,534
2 | 78, 39, 534 |
3 | 39, 39, 267 |
13 | 13, 13, 89 |
1, 1, 89 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 1 x 89 = 6942
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/6942
Therefore, the GCF of Fractions 58/78,878/39,168/534 is 2/6942
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 78,39,534 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,39,534) = 3
common factors(in case of two or more numbers have common factors) = 78
GCF(78,39,534) x common factors =3 x 78 = 234
LCM(78,39,534) = ( 78 × 39 × 534 ) / 234
LCM(78,39,534) = 1624428 / 234
LCM(78,39,534) = 6942
