Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 51/23,56/61,67/51
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 51/23,56/61,67/51, numerators are 51,56,67
Denominators are 23,61,51
The GCF of 51,56,67 is 1 .
LCM of 23,61,51 is 71553.
The greatest common factor of 51/23,56/61,67/51 = [GCF of 51,56,67]/[LCM of 23,61,51]= 1/71553
Therefore, the GCF of 51/23,56/61,67/51 is 1/71553.
To find the highest common factor of 51,56,67, we have to find the factors of both numbers and list the highest common factor.
The factors of 51 are 1, 3, 17, 51
The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56
The factors of 67 are 1, 67
The HCF of 51,56,67 is 1.
Lets's calculate GCF of 51,56,67
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 51
:1,3,17,51
Now, list down the factors of 56
:1,2,4,7,8,14,28,56
Now, list down the factors of 67
:1,67
Greatest Common Factor
We found the factors 51,56,67 . The biggest common factor number is the GCF number.
So the greatest common factor 51,56,67 is 1.
Lets's calculate LCM of 23,61,51
Given numbers has no common factors except 1. So, there LCM is their product i.e 71553
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/71553
Therefore, the GCF of Fractions 51/23,56/61,67/51 is 1/71553
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 23,61,51 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(23,61,51) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(23,61,51) x common factors =1 x 1 = 1
LCM(23,61,51) = ( 23 × 61 × 51 ) / 1
LCM(23,61,51) = 71553 / 1
LCM(23,61,51) = 71553
