Lets's calculate LCM of 420,4774
2 | 420, 4774 |
7 | 210, 2387 |
30, 341 |
∴ So the LCM of the given numbers is 2 x 7 x 30 x 341 = 143220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/143220
Therefore, the GCF of Fractions 7874/420,1734/4774 is 2/143220
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 420,4774 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,4774) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(420,4774) x common factors =14 x 1 = 14
LCM(420,4774) = ( 420 × 4774 ) / 14
LCM(420,4774) = 2005080 / 14
LCM(420,4774) = 143220
