Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 11/737,21/213
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 11/737,21/213, numerators are 11,21
Denominators are 737,213
The GCF of 11,21 is 1 .
LCM of 737,213 is 156981.
The greatest common factor of 11/737,21/213 = [GCF of 11,21]/[LCM of 737,213]= 1/156981
Therefore, the GCF of 11/737,21/213 is 1/156981.
To find the highest common factor of 11,21, we have to find the factors of both numbers and list the highest common factor.
The factors of 11 are 1, 11
The factors of 21 are 1, 3, 7, 21
The HCF of 11,21 is 1.
Lets's calculate GCF of 11,21
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 737,213
Given numbers has no common factors except 1. So, there LCM is their product i.e 156981
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/156981
Therefore, the GCF of Fractions 11/737,21/213 is 1/156981
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 737,213 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(737,213) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(737,213) x common factors =1 x 1 = 1
LCM(737,213) = ( 737 × 213 ) / 1
LCM(737,213) = 156981 / 1
LCM(737,213) = 156981
