Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 392/30,1706/989
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 392,1706
Greatest Common Factor of Numerators i.e. GCF of 392,1706 is 2 .
LCM of Denominators means LCM of 30,989 as per the given fractions.
LCM of 30,989 is 29670 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 392,1706
2 | 392, 1706 |
196, 853 |
∴ So the GCF of the given numbers is 2 = 2

1,2,4,7,8,14,28,49,56,98,196,392
Factors of 1706
List of positive integer factors of 1706 that divides 1706 without a remainder.
1,2,853,1706
Greatest Common Factor
We found the factors 392,1706 . The biggest common factor number is the GCF number.
So the greatest common factor 392,1706 is 2.
Lets's calculate LCM of 30,989
Given numbers has no common factors except 1. So, there LCM is their product i.e 29670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/29670
Therefore, the GCF of Fractions 392/30,1706/989 is 2/29670
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 30,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(30,989) x common factors =1 x 1 = 1
LCM(30,989) = ( 30 × 989 ) / 1
LCM(30,989) = 29670 / 1
LCM(30,989) = 29670
