So the greatest common factor 400,156 is 4.
Lets's calculate LCM of 664,258
2 | 664, 258 |
332, 129 |
∴ So the LCM of the given numbers is 2 x 332 x 129 = 85656
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/85656
Therefore, the GCF of Fractions 400/664,156/258 is 4/85656
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 664,258 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(664,258) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(664,258) x common factors =2 x 1 = 2
LCM(664,258) = ( 664 × 258 ) / 2
LCM(664,258) = 171312 / 2
LCM(664,258) = 85656
