Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 172/70,946/8557
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 172,946
Greatest Common Factor of Numerators i.e. GCF of 172,946 is 86 .
LCM of Denominators means LCM of 70,8557 as per the given fractions.
LCM of 70,8557 is 598990 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 172,946
2 | 172, 946 |
43 | 86, 473 |
2, 11 |
∴ So the GCF of the given numbers is 2 x 43 = 86
Factors of 172
List of positive integer factors of 172 that divides 172 without a remainder.
1,2,4,43,86,172
Factors of 946
List of positive integer factors of 946 that divides 946 without a remainder.
1,2,11,22,43,86,473,946
Greatest Common Factor
We found the factors 172,946 . The biggest common factor number is the GCF number.
So the greatest common factor 172,946 is 86.
Lets's calculate LCM of 70,8557
Given numbers has no common factors except 1. So, there LCM is their product i.e 598990
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 86/598990
Therefore, the GCF of Fractions 172/70,946/8557 is 86/598990
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 70,8557 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,8557) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(70,8557) x common factors =1 x 1 = 1
LCM(70,8557) = ( 70 × 8557 ) / 1
LCM(70,8557) = 598990 / 1
LCM(70,8557) = 598990
Here are some samples of GCF of Fractions calculations.
