Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 14/86,90/98,704/79
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 14,90,704
Greatest Common Factor of Numerators i.e. GCF of 14,90,704 is 2 .
LCM of Denominators means LCM of 86,98,79 as per the given fractions.
LCM of 86,98,79 is 332906 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 14,90,704
2 | 14, 90, 704 |
7, 45, 352 |
∴ So the GCF of the given numbers is 2 = 2

1,2,4,8,11,16,22,32,44,64,88,176,352,704
Greatest Common Factor
We found the factors 14,90,704 . The biggest common factor number is the GCF number.
So the greatest common factor 14,90,704 is 2.
Lets's calculate LCM of 86,98,79
2 | 86, 98, 79 |
43, 49, 79 |
∴ So the LCM of the given numbers is 2 x 43 x 49 x 79 = 332906
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/332906
Therefore, the GCF of Fractions 14/86,90/98,704/79 is 2/332906
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 86,98,79 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,98,79) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(86,98,79) x common factors =1 x 2 = 2
LCM(86,98,79) = ( 86 × 98 × 79 ) / 2
LCM(86,98,79) = 665812 / 2
LCM(86,98,79) = 332906
