Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 290/89,3320/940
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 290,3320
Greatest Common Factor of Numerators i.e. GCF of 290,3320 is 10 .
LCM of Denominators means LCM of 89,940 as per the given fractions.
LCM of 89,940 is 83660 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 290,3320
2 | 290, 3320 |
5 | 145, 1660 |
29, 332 |
∴ So the GCF of the given numbers is 2 x 5 = 10

Factors of 3320
List of positive integer factors of 3320 that divides 3320 without a remainder.
1,2,4,5,8,10,20,40,83,166,332,415,664,830,1660,3320
Greatest Common Factor
We found the factors 290,3320 . The biggest common factor number is the GCF number.
So the greatest common factor 290,3320 is 10.
Lets's calculate LCM of 89,940
Given numbers has no common factors except 1. So, there LCM is their product i.e 83660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/83660
Therefore, the GCF of Fractions 290/89,3320/940 is 10/83660
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 89,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,940) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,940) x common factors =1 x 1 = 1
LCM(89,940) = ( 89 × 940 ) / 1
LCM(89,940) = 83660 / 1
LCM(89,940) = 83660
