Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 70/38,70/81,42/81,14/964
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 70,70,42,14
Greatest Common Factor of Numerators i.e. GCF of 70,70,42,14 is 14 .
LCM of Denominators means LCM of 38,81,81,964 as per the given fractions.
LCM of 38,81,81,964 is 1483596 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 70,70,42,14
2 | 70, 70, 42, 14 |
7 | 35, 35, 21, 7 |
5, 5, 3, 1 |
∴ So the GCF of the given numbers is 2 x 7 = 14

Greatest Common Factor
We found the factors 70,70,42,14 . The biggest common factor number is the GCF number.
So the greatest common factor 70,70,42,14 is 14.
Lets's calculate LCM of 38,81,81,964
2 | 38, 81, 81, 964 |
3 | 19, 81, 81, 482 |
3 | 19, 27, 27, 482 |
3 | 19, 9, 9, 482 |
3 | 19, 3, 3, 482 |
19, 1, 1, 482 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 3 x 19 x 1 x 1 x 482 = 1483596
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/1483596
Therefore, the GCF of Fractions 70/38,70/81,42/81,14/964 is 14/1483596
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 38,81,81,964 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,81,81,964) = 1
common factors(in case of two or more numbers have common factors) = 162
GCF(38,81,81,964) x common factors =1 x 162 = 162
LCM(38,81,81,964) = ( 38 × 81 × 81 × 964 ) / 162
LCM(38,81,81,964) = 240342552 / 162
LCM(38,81,81,964) = 1483596
