So the greatest common factor 69,39 is 3.
Lets's calculate LCM of 905,7964
181 | 905, 7964 |
5, 44 |
∴ So the LCM of the given numbers is 181 x 5 x 44 = 39820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/39820
Therefore, the GCF of Fractions 69/905,39/7964 is 3/39820
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 905,7964 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,7964) = 181
common factors(in case of two or more numbers have common factors) = 1
GCF(905,7964) x common factors =181 x 1 = 181
LCM(905,7964) = ( 905 × 7964 ) / 181
LCM(905,7964) = 7207420 / 181
LCM(905,7964) = 39820
