Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 81/973,992/520
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 81,992
Greatest Common Factor of Numerators i.e. GCF of 81,992 is 1 .
LCM of Denominators means LCM of 973,520 as per the given fractions.
LCM of 973,520 is 505960 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 81,992
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 81
List of positive integer factors of 81 that divides 81 without a remainder.
1,3,9,27,81
Factors of 992
List of positive integer factors of 992 that divides 992 without a remainder.
1,2,4,8,16,31,32,62,124,248,496,992
Greatest Common Factor
We found the factors 81,992 . The biggest common factor number is the GCF number.
So the greatest common factor 81,992 is 1.
Lets's calculate LCM of 973,520
Given numbers has no common factors except 1. So, there LCM is their product i.e 505960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/505960
Therefore, the GCF of Fractions 81/973,992/520 is 1/505960
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 973,520 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(973,520) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(973,520) x common factors =1 x 1 = 1
LCM(973,520) = ( 973 × 520 ) / 1
LCM(973,520) = 505960 / 1
LCM(973,520) = 505960
