Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 55/645,43/890
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 55/645,43/890, numerators are 55,43
Denominators are 645,890
The GCF of 55,43 is 1 .
LCM of 645,890 is 114810.
The greatest common factor of 55/645,43/890 = [GCF of 55,43]/[LCM of 645,890]= 1/114810
Therefore, the GCF of 55/645,43/890 is 1/114810.
To find the highest common factor of 55,43, we have to find the factors of both numbers and list the highest common factor.
The factors of 55 are 1, 5, 11, 55
The factors of 43 are 1, 43
The HCF of 55,43 is 1.
Lets's calculate GCF of 55,43
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 645,890
5 | 645, 890 |
129, 178 |
∴ So the LCM of the given numbers is 5 x 129 x 178 = 114810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/114810
Therefore, the GCF of Fractions 55/645,43/890 is 1/114810
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 645,890 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,890) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(645,890) x common factors =5 x 1 = 5
LCM(645,890) = ( 645 × 890 ) / 5
LCM(645,890) = 574050 / 5
LCM(645,890) = 114810
