Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 421/390,2047/864
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 421,2047
Greatest Common Factor of Numerators i.e. GCF of 421,2047 is 1 .
LCM of Denominators means LCM of 390,864 as per the given fractions.
LCM of 390,864 is 56160 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 421,2047
∴ So GCF of numbers is 1 because of no common factors present between them.

1,421
Factors of 2047
List of positive integer factors of 2047 that divides 2047 without a remainder.
1,23,89,2047
Greatest Common Factor
We found the factors 421,2047 . The biggest common factor number is the GCF number.
So the greatest common factor 421,2047 is 1.
Lets's calculate LCM of 390,864
2 | 390, 864 |
3 | 195, 432 |
65, 144 |
∴ So the LCM of the given numbers is 2 x 3 x 65 x 144 = 56160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/56160
Therefore, the GCF of Fractions 421/390,2047/864 is 1/56160
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 390,864 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,864) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(390,864) x common factors =6 x 1 = 6
LCM(390,864) = ( 390 × 864 ) / 6
LCM(390,864) = 336960 / 6
LCM(390,864) = 56160
