Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 87/207,477/946
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 87,477
Greatest Common Factor of Numerators i.e. GCF of 87,477 is 3 .
LCM of Denominators means LCM of 207,946 as per the given fractions.
LCM of 207,946 is 195822 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 87,477
3 | 87, 477 |
29, 159 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 87
List of positive integer factors of 87 that divides 87 without a remainder.
1,3,29,87
Factors of 477
List of positive integer factors of 477 that divides 477 without a remainder.
1,3,9,53,159,477
Greatest Common Factor
We found the factors 87,477 . The biggest common factor number is the GCF number.
So the greatest common factor 87,477 is 3.
Lets's calculate LCM of 207,946
Given numbers has no common factors except 1. So, there LCM is their product i.e 195822
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/195822
Therefore, the GCF of Fractions 87/207,477/946 is 3/195822
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 207,946 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(207,946) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(207,946) x common factors =1 x 1 = 1
LCM(207,946) = ( 207 × 946 ) / 1
LCM(207,946) = 195822 / 1
LCM(207,946) = 195822
