Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 425/662,1691/541
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 425,1691
Greatest Common Factor of Numerators i.e. GCF of 425,1691 is 1 .
LCM of Denominators means LCM of 662,541 as per the given fractions.
LCM of 662,541 is 358142 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 425,1691
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 425
List of positive integer factors of 425 that divides 425 without a remainder.
1,5,17,25,85,425
Factors of 1691
List of positive integer factors of 1691 that divides 1691 without a remainder.
1,19,89,1691
Greatest Common Factor
We found the factors 425,1691 . The biggest common factor number is the GCF number.
So the greatest common factor 425,1691 is 1.
Lets's calculate LCM of 662,541
Given numbers has no common factors except 1. So, there LCM is their product i.e 358142
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/358142
Therefore, the GCF of Fractions 425/662,1691/541 is 1/358142
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 662,541 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(662,541) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(662,541) x common factors =1 x 1 = 1
LCM(662,541) = ( 662 × 541 ) / 1
LCM(662,541) = 358142 / 1
LCM(662,541) = 358142
