Lets's calculate LCM of 415,9315
5 | 415, 9315 |
83, 1863 |
∴ So the LCM of the given numbers is 5 x 83 x 1863 = 773145
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/773145
Therefore, the GCF of Fractions 42/415,4029/9315 is 3/773145
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 415,9315 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(415,9315) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(415,9315) x common factors =5 x 1 = 5
LCM(415,9315) = ( 415 × 9315 ) / 5
LCM(415,9315) = 3865725 / 5
LCM(415,9315) = 773145
