Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 851/38,490/6969
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 851,490
Greatest Common Factor of Numerators i.e. GCF of 851,490 is 1 .
LCM of Denominators means LCM of 38,6969 as per the given fractions.
LCM of 38,6969 is 264822 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 851,490
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 851
List of positive integer factors of 851 that divides 851 without a remainder.
1,23,37,851
Factors of 490
List of positive integer factors of 490 that divides 490 without a remainder.
1,2,5,7,10,14,35,49,70,98,245,490
Greatest Common Factor
We found the factors 851,490 . The biggest common factor number is the GCF number.
So the greatest common factor 851,490 is 1.
Lets's calculate LCM of 38,6969
Given numbers has no common factors except 1. So, there LCM is their product i.e 264822
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/264822
Therefore, the GCF of Fractions 851/38,490/6969 is 1/264822
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 38,6969 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,6969) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(38,6969) x common factors =1 x 1 = 1
LCM(38,6969) = ( 38 × 6969 ) / 1
LCM(38,6969) = 264822 / 1
LCM(38,6969) = 264822
