So the greatest common factor 434,7756 is 14.
Lets's calculate LCM of 812,916
2 | 812, 916 |
2 | 406, 458 |
203, 229 |
∴ So the LCM of the given numbers is 2 x 2 x 203 x 229 = 185948
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/185948
Therefore, the GCF of Fractions 434/812,7756/916 is 14/185948
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 812,916 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(812,916) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(812,916) x common factors =4 x 1 = 4
LCM(812,916) = ( 812 × 916 ) / 4
LCM(812,916) = 743792 / 4
LCM(812,916) = 185948
