Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 7/90,473/81,626/15
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 7,473,626
Greatest Common Factor of Numerators i.e. GCF of 7,473,626 is 1 .
LCM of Denominators means LCM of 90,81,15 as per the given fractions.
LCM of 90,81,15 is 810 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 7,473,626
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 7

1,7
Factors of 473
List of positive integer factors of 473 that divides 473 without a remainder.
1,11,43,473
Factors of 626
List of positive integer factors of 626 that divides 626 without a remainder.
1,2,313,626
Greatest Common Factor
We found the factors 7,473,626 . The biggest common factor number is the GCF number.
So the greatest common factor 7,473,626 is 1.
Lets's calculate LCM of 90,81,15
3 | 90, 81, 15 |
3 | 30, 27, 5 |
5 | 10, 9, 5 |
2, 9, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 2 x 9 x 1 = 810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/810
Therefore, the GCF of Fractions 7/90,473/81,626/15 is 1/810
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 90,81,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,81,15) = 3
common factors(in case of two or more numbers have common factors) = 45
GCF(90,81,15) x common factors =3 x 45 = 135
LCM(90,81,15) = ( 90 × 81 × 15 ) / 135
LCM(90,81,15) = 109350 / 135
LCM(90,81,15) = 810
