Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 39/642,428/247
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 39,428
Greatest Common Factor of Numerators i.e. GCF of 39,428 is 1 .
LCM of Denominators means LCM of 642,247 as per the given fractions.
LCM of 642,247 is 158574 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 39,428
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 39
List of positive integer factors of 39 that divides 39 without a remainder.
1,3,13,39
Factors of 428
List of positive integer factors of 428 that divides 428 without a remainder.
1,2,4,107,214,428
Greatest Common Factor
We found the factors 39,428 . The biggest common factor number is the GCF number.
So the greatest common factor 39,428 is 1.
Lets's calculate LCM of 642,247
Given numbers has no common factors except 1. So, there LCM is their product i.e 158574
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/158574
Therefore, the GCF of Fractions 39/642,428/247 is 1/158574
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 642,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(642,247) x common factors =1 x 1 = 1
LCM(642,247) = ( 642 × 247 ) / 1
LCM(642,247) = 158574 / 1
LCM(642,247) = 158574
