Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 97/311,91/693
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 97/311,91/693, numerators are 97,91
Denominators are 311,693
The GCF of 97,91 is 1 .
LCM of 311,693 is 215523.
The greatest common factor of 97/311,91/693 = [GCF of 97,91]/[LCM of 311,693]= 1/215523
Therefore, the GCF of 97/311,91/693 is 1/215523.
To find the highest common factor of 97,91, we have to find the factors of both numbers and list the highest common factor.
The factors of 97 are 1, 97
The factors of 91 are 1, 7, 13, 91
The HCF of 97,91 is 1.
Lets's calculate GCF of 97,91
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 311,693
Given numbers has no common factors except 1. So, there LCM is their product i.e 215523
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/215523
Therefore, the GCF of Fractions 97/311,91/693 is 1/215523
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 311,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(311,693) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(311,693) x common factors =1 x 1 = 1
LCM(311,693) = ( 311 × 693 ) / 1
LCM(311,693) = 215523 / 1
LCM(311,693) = 215523
