So the greatest common factor 450,954,640 is 2.
Lets's calculate LCM of 77,45,40
5 | 77, 45, 40 |
77, 9, 8 |
∴ So the LCM of the given numbers is 5 x 77 x 9 x 8 = 27720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/27720
Therefore, the GCF of Fractions 450/77,954/45,640/40 is 2/27720
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 77,45,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,45,40) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(77,45,40) x common factors =1 x 5 = 5
LCM(77,45,40) = ( 77 × 45 × 40 ) / 5
LCM(77,45,40) = 138600 / 5
LCM(77,45,40) = 27720
