So the greatest common factor 225,510 is 15.
Lets's calculate LCM of 258,722
2 | 258, 722 |
129, 361 |
∴ So the LCM of the given numbers is 2 x 129 x 361 = 93138
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/93138
Therefore, the GCF of Fractions 225/258,510/722 is 15/93138
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 258,722 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(258,722) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(258,722) x common factors =2 x 1 = 2
LCM(258,722) = ( 258 × 722 ) / 2
LCM(258,722) = 186276 / 2
LCM(258,722) = 93138
