We found the factors 414,116,468 . The biggest common factor number is the GCF number.
So the greatest common factor 414,116,468 is 2.
Lets's calculate LCM of 78,39,21
3 | 78, 39, 21 |
13 | 26, 13, 7 |
2, 1, 7 |
∴ So the LCM of the given numbers is 3 x 13 x 2 x 1 x 7 = 546
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/546
Therefore, the GCF of Fractions 414/78,116/39,468/21 is 2/546
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 78,39,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,39,21) = 3
common factors(in case of two or more numbers have common factors) = 39
GCF(78,39,21) x common factors =3 x 39 = 117
LCM(78,39,21) = ( 78 × 39 × 21 ) / 117
LCM(78,39,21) = 63882 / 117
LCM(78,39,21) = 546
