Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 23/991,21/182
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 23/991,21/182, numerators are 23,21
Denominators are 991,182
The GCF of 23,21 is 1 .
LCM of 991,182 is 180362.
The greatest common factor of 23/991,21/182 = [GCF of 23,21]/[LCM of 991,182]= 1/180362
Therefore, the GCF of 23/991,21/182 is 1/180362.
To find the highest common factor of 23,21, we have to find the factors of both numbers and list the highest common factor.
The factors of 23 are 1, 23
The factors of 21 are 1, 3, 7, 21
The HCF of 23,21 is 1.
Lets's calculate GCF of 23,21
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 991,182
Given numbers has no common factors except 1. So, there LCM is their product i.e 180362
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/180362
Therefore, the GCF of Fractions 23/991,21/182 is 1/180362
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 991,182 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(991,182) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(991,182) x common factors =1 x 1 = 1
LCM(991,182) = ( 991 × 182 ) / 1
LCM(991,182) = 180362 / 1
LCM(991,182) = 180362
