Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/422,53/4164
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 21/422,53/4164, numerators are 21,53
Denominators are 422,4164
The GCF of 21,53 is 1 .
LCM of 422,4164 is 878604.
The greatest common factor of 21/422,53/4164 = [GCF of 21,53]/[LCM of 422,4164]= 1/878604
Therefore, the GCF of 21/422,53/4164 is 1/878604.
To find the highest common factor of 21,53, we have to find the factors of both numbers and list the highest common factor.
The factors of 21 are 1, 3, 7, 21
The factors of 53 are 1, 53
The HCF of 21,53 is 1.
Lets's calculate GCF of 21,53
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 422,4164
2 | 422, 4164 |
211, 2082 |
∴ So the LCM of the given numbers is 2 x 211 x 2082 = 878604
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/878604
Therefore, the GCF of Fractions 21/422,53/4164 is 1/878604
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 422,4164 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(422,4164) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(422,4164) x common factors =2 x 1 = 2
LCM(422,4164) = ( 422 × 4164 ) / 2
LCM(422,4164) = 1757208 / 2
LCM(422,4164) = 878604
