Greatest Common Factor
We found the factors 805,7311 . The biggest common factor number is the GCF number.
So the greatest common factor 805,7311 is 1.
Lets's calculate LCM of 912,2240
2 | 912, 2240 |
2 | 456, 1120 |
2 | 228, 560 |
2 | 114, 280 |
57, 140 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 57 x 140 = 127680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/127680
Therefore, the GCF of Fractions 805/912,7311/2240 is 1/127680
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 912,2240 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(912,2240) = 16
common factors(in case of two or more numbers have common factors) = 1
GCF(912,2240) x common factors =16 x 1 = 16
LCM(912,2240) = ( 912 × 2240 ) / 16
LCM(912,2240) = 2042880 / 16
LCM(912,2240) = 127680
