Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 747/407,830/492
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 747,830
Greatest Common Factor of Numerators i.e. GCF of 747,830 is 83 .
LCM of Denominators means LCM of 407,492 as per the given fractions.
LCM of 407,492 is 200244 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 747,830
83 | 747, 830 |
9, 10 |
∴ So the GCF of the given numbers is 83 = 83

1,3,9,83,249,747
Factors of 830
List of positive integer factors of 830 that divides 830 without a remainder.
1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 747,830 . The biggest common factor number is the GCF number.
So the greatest common factor 747,830 is 83.
Lets's calculate LCM of 407,492
Given numbers has no common factors except 1. So, there LCM is their product i.e 200244
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 83/200244
Therefore, the GCF of Fractions 747/407,830/492 is 83/200244
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 407,492 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(407,492) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(407,492) x common factors =1 x 1 = 1
LCM(407,492) = ( 407 × 492 ) / 1
LCM(407,492) = 200244 / 1
LCM(407,492) = 200244
Here are some samples of GCF of Fractions calculations.
