Lets's calculate LCM of 248,872
2 | 248, 872 |
2 | 124, 436 |
2 | 62, 218 |
31, 109 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 31 x 109 = 27032
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/27032
Therefore, the GCF of Fractions 371/248,357/872 is 7/27032
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 248,872 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(248,872) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(248,872) x common factors =8 x 1 = 8
LCM(248,872) = ( 248 × 872 ) / 8
LCM(248,872) = 216256 / 8
LCM(248,872) = 27032
