Greatest Common Factor
We found the factors 5,90,70,282 . The biggest common factor number is the GCF number.
So the greatest common factor 5,90,70,282 is 1.
Lets's calculate LCM of 42,58,900,510
2 | 42, 58, 900, 510 |
3 | 21, 29, 450, 255 |
5 | 7, 29, 150, 85 |
7, 29, 30, 17 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 29 x 30 x 17 = 3105900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3105900
Therefore, the GCF of Fractions 5/42,90/58,70/900,282/510 is 1/3105900
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 42,58,900,510 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,58,900,510) = 2
common factors(in case of two or more numbers have common factors) = 180
GCF(42,58,900,510) x common factors =2 x 180 = 360
LCM(42,58,900,510) = ( 42 × 58 × 900 × 510 ) / 360
LCM(42,58,900,510) = 1118124000 / 360
LCM(42,58,900,510) = 3105900
