Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 280/42,560/996
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 280,560
Greatest Common Factor of Numerators i.e. GCF of 280,560 is 280 .
LCM of Denominators means LCM of 42,996 as per the given fractions.
LCM of 42,996 is 6972 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 280,560
2 | 280, 560 |
2 | 140, 280 |
2 | 70, 140 |
5 | 35, 70 |
7 | 7, 14 |
1, 2 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 5 x 7 = 280

List of positive integer factors of 280 that divides 280 without a remainder.
1,2,4,5,7,8,10,14,20,28,35,40,56,70,140,280
Factors of 560
List of positive integer factors of 560 that divides 560 without a remainder.
1,2,4,5,7,8,10,14,16,20,28,35,40,56,70,80,112,140,280,560
Greatest Common Factor
We found the factors 280,560 . The biggest common factor number is the GCF number.
So the greatest common factor 280,560 is 280.
Lets's calculate LCM of 42,996
2 | 42, 996 |
3 | 21, 498 |
7, 166 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 166 = 6972
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 280/6972
Therefore, the GCF of Fractions 280/42,560/996 is 280/6972
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 42,996 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,996) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(42,996) x common factors =6 x 1 = 6
LCM(42,996) = ( 42 × 996 ) / 6
LCM(42,996) = 41832 / 6
LCM(42,996) = 6972
