Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 401/120,730/489
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 401,730
Greatest Common Factor of Numerators i.e. GCF of 401,730 is 1 .
LCM of Denominators means LCM of 120,489 as per the given fractions.
LCM of 120,489 is 19560 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 401,730
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 401

1,401
Factors of 730
List of positive integer factors of 730 that divides 730 without a remainder.
1,2,5,10,73,146,365,730
Greatest Common Factor
We found the factors 401,730 . The biggest common factor number is the GCF number.
So the greatest common factor 401,730 is 1.
Lets's calculate LCM of 120,489
3 | 120, 489 |
40, 163 |
∴ So the LCM of the given numbers is 3 x 40 x 163 = 19560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19560
Therefore, the GCF of Fractions 401/120,730/489 is 1/19560
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 120,489 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(120,489) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(120,489) x common factors =3 x 1 = 3
LCM(120,489) = ( 120 × 489 ) / 3
LCM(120,489) = 58680 / 3
LCM(120,489) = 19560
