So the greatest common factor 7647,1986 is 3.
Lets's calculate LCM of 905,970
5 | 905, 970 |
181, 194 |
∴ So the LCM of the given numbers is 5 x 181 x 194 = 175570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/175570
Therefore, the GCF of Fractions 7647/905,1986/970 is 3/175570
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 905,970 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,970) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(905,970) x common factors =5 x 1 = 5
LCM(905,970) = ( 905 × 970 ) / 5
LCM(905,970) = 877850 / 5
LCM(905,970) = 175570
