So the greatest common factor 123,942 is 3.
Lets's calculate LCM of 880,440
2 | 880, 440 |
2 | 440, 220 |
2 | 110, 220 |
5 | 55, 110 |
11 | 11, 22 |
1, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 11 x 1 x 2 = 880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/880
Therefore, the GCF of Fractions 123/880,942/440 is 3/880
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 880,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(880,440) = 440
common factors(in case of two or more numbers have common factors) = 1
GCF(880,440) x common factors =440 x 1 = 440
LCM(880,440) = ( 880 × 440 ) / 440
LCM(880,440) = 387200 / 440
LCM(880,440) = 880
