Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 72/673,153/642
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 72,153
Greatest Common Factor of Numerators i.e. GCF of 72,153 is 9 .
LCM of Denominators means LCM of 673,642 as per the given fractions.
LCM of 673,642 is 432066 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 72,153
3 | 72, 153 |
3 | 24, 51 |
8, 17 |
∴ So the GCF of the given numbers is 3 x 3 = 9

Factors of 153
List of positive integer factors of 153 that divides 153 without a remainder.
1,3,9,17,51,153
Greatest Common Factor
We found the factors 72,153 . The biggest common factor number is the GCF number.
So the greatest common factor 72,153 is 9.
Lets's calculate LCM of 673,642
Given numbers has no common factors except 1. So, there LCM is their product i.e 432066
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/432066
Therefore, the GCF of Fractions 72/673,153/642 is 9/432066
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 673,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(673,642) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(673,642) x common factors =1 x 1 = 1
LCM(673,642) = ( 673 × 642 ) / 1
LCM(673,642) = 432066 / 1
LCM(673,642) = 432066
Here are some samples of GCF of Fractions calculations.
