Greatest Common Factor
We found the factors 80,282,372 . The biggest common factor number is the GCF number.
So the greatest common factor 80,282,372 is 2.
Lets's calculate LCM of 71,90,40
2 | 71, 90, 40 |
5 | 71, 45, 20 |
71, 9, 4 |
∴ So the LCM of the given numbers is 2 x 5 x 71 x 9 x 4 = 25560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/25560
Therefore, the GCF of Fractions 80/71,282/90,372/40 is 2/25560
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 71,90,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,90,40) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(71,90,40) x common factors =1 x 10 = 10
LCM(71,90,40) = ( 71 × 90 × 40 ) / 10
LCM(71,90,40) = 255600 / 10
LCM(71,90,40) = 25560
