Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 97/550,81/7405
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 97/550,81/7405, numerators are 97,81
Denominators are 550,7405
The GCF of 97,81 is 1 .
LCM of 550,7405 is 814550.
The greatest common factor of 97/550,81/7405 = [GCF of 97,81]/[LCM of 550,7405]= 1/814550
Therefore, the GCF of 97/550,81/7405 is 1/814550.
To find the highest common factor of 97,81, we have to find the factors of both numbers and list the highest common factor.
The factors of 97 are 1, 97
The factors of 81 are 1, 3, 9, 27, 81
The HCF of 97,81 is 1.
Lets's calculate GCF of 97,81
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 550,7405
5 | 550, 7405 |
110, 1481 |
∴ So the LCM of the given numbers is 5 x 110 x 1481 = 814550
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/814550
Therefore, the GCF of Fractions 97/550,81/7405 is 1/814550
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 550,7405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(550,7405) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(550,7405) x common factors =5 x 1 = 5
LCM(550,7405) = ( 550 × 7405 ) / 5
LCM(550,7405) = 4072750 / 5
LCM(550,7405) = 814550
