So the greatest common factor 558,897 is 3.
Lets's calculate LCM of 420,334
2 | 420, 334 |
210, 167 |
∴ So the LCM of the given numbers is 2 x 210 x 167 = 70140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/70140
Therefore, the GCF of Fractions 558/420,897/334 is 3/70140
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 420,334 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,334) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(420,334) x common factors =2 x 1 = 2
LCM(420,334) = ( 420 × 334 ) / 2
LCM(420,334) = 140280 / 2
LCM(420,334) = 70140
