So the greatest common factor 260,312 is 52.
Lets's calculate LCM of 310,812
2 | 310, 812 |
155, 406 |
∴ So the LCM of the given numbers is 2 x 155 x 406 = 125860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 52/125860
Therefore, the GCF of Fractions 260/310,312/812 is 52/125860
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 310,812 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(310,812) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(310,812) x common factors =2 x 1 = 2
LCM(310,812) = ( 310 × 812 ) / 2
LCM(310,812) = 251720 / 2
LCM(310,812) = 125860
