Lets's calculate LCM of 812,284
2 | 812, 284 |
2 | 406, 142 |
203, 71 |
∴ So the LCM of the given numbers is 2 x 2 x 203 x 71 = 57652
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/57652
Therefore, the GCF of Fractions 439/812,785/284 is 1/57652
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 812,284 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(812,284) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(812,284) x common factors =4 x 1 = 4
LCM(812,284) = ( 812 × 284 ) / 4
LCM(812,284) = 230608 / 4
LCM(812,284) = 57652
