We found the factors 807,921 . The biggest common factor number is the GCF number.
So the greatest common factor 807,921 is 3.
Lets's calculate LCM of 412,852
2 | 412, 852 |
2 | 206, 426 |
103, 213 |
∴ So the LCM of the given numbers is 2 x 2 x 103 x 213 = 87756
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/87756
Therefore, the GCF of Fractions 807/412,921/852 is 3/87756
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 412,852 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(412,852) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(412,852) x common factors =4 x 1 = 4
LCM(412,852) = ( 412 × 852 ) / 4
LCM(412,852) = 351024 / 4
LCM(412,852) = 87756
