Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 634/390,316/461
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 634,316
Greatest Common Factor of Numerators i.e. GCF of 634,316 is 2 .
LCM of Denominators means LCM of 390,461 as per the given fractions.
LCM of 390,461 is 179790 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 634,316
2 | 634, 316 |
317, 158 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 634
List of positive integer factors of 634 that divides 634 without a remainder.
1,2,317,634
Factors of 316
List of positive integer factors of 316 that divides 316 without a remainder.
1,2,4,79,158,316
Greatest Common Factor
We found the factors 634,316 . The biggest common factor number is the GCF number.
So the greatest common factor 634,316 is 2.
Lets's calculate LCM of 390,461
Given numbers has no common factors except 1. So, there LCM is their product i.e 179790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/179790
Therefore, the GCF of Fractions 634/390,316/461 is 2/179790
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 390,461 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,461) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(390,461) x common factors =1 x 1 = 1
LCM(390,461) = ( 390 × 461 ) / 1
LCM(390,461) = 179790 / 1
LCM(390,461) = 179790
