Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 77/131,31/298
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 77/131,31/298, numerators are 77,31
Denominators are 131,298
The GCF of 77,31 is 1 .
LCM of 131,298 is 39038.
The greatest common factor of 77/131,31/298 = [GCF of 77,31]/[LCM of 131,298]= 1/39038
Therefore, the GCF of 77/131,31/298 is 1/39038.
To find the highest common factor of 77,31, we have to find the factors of both numbers and list the highest common factor.
The factors of 77 are 1, 7, 11, 77
The factors of 31 are 1, 31
The HCF of 77,31 is 1.
Lets's calculate GCF of 77,31
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 131,298
Given numbers has no common factors except 1. So, there LCM is their product i.e 39038
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39038
Therefore, the GCF of Fractions 77/131,31/298 is 1/39038
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 131,298 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(131,298) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(131,298) x common factors =1 x 1 = 1
LCM(131,298) = ( 131 × 298 ) / 1
LCM(131,298) = 39038 / 1
LCM(131,298) = 39038
