Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 13/902,57/1406
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 13/902,57/1406, numerators are 13,57
Denominators are 902,1406
The GCF of 13,57 is 1 .
LCM of 902,1406 is 634106.
The greatest common factor of 13/902,57/1406 = [GCF of 13,57]/[LCM of 902,1406]= 1/634106
Therefore, the GCF of 13/902,57/1406 is 1/634106.
To find the highest common factor of 13,57, we have to find the factors of both numbers and list the highest common factor.
The factors of 13 are 1, 13
The factors of 57 are 1, 3, 19, 57
The HCF of 13,57 is 1.
Lets's calculate GCF of 13,57
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 902,1406
2 | 902, 1406 |
451, 703 |
∴ So the LCM of the given numbers is 2 x 451 x 703 = 634106
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/634106
Therefore, the GCF of Fractions 13/902,57/1406 is 1/634106
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 902,1406 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(902,1406) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(902,1406) x common factors =2 x 1 = 2
LCM(902,1406) = ( 902 × 1406 ) / 2
LCM(902,1406) = 1268212 / 2
LCM(902,1406) = 634106
