Lets's calculate LCM of 412,428
2 | 412, 428 |
2 | 206, 214 |
103, 107 |
∴ So the LCM of the given numbers is 2 x 2 x 103 x 107 = 44084
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/44084
Therefore, the GCF of Fractions 122/412,945/428 is 1/44084
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 412,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(412,428) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(412,428) x common factors =4 x 1 = 4
LCM(412,428) = ( 412 × 428 ) / 4
LCM(412,428) = 176336 / 4
LCM(412,428) = 44084
