So the greatest common factor 40,21,928 is 1.
Lets's calculate LCM of 421,686,800
2 | 421, 686, 800 |
421, 343, 400 |
∴ So the LCM of the given numbers is 2 x 421 x 343 x 400 = 115522400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/115522400
Therefore, the GCF of Fractions 40/421,21/686,928/800 is 1/115522400
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 421,686,800 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,686,800) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(421,686,800) x common factors =1 x 2 = 2
LCM(421,686,800) = ( 421 × 686 × 800 ) / 2
LCM(421,686,800) = 231044800 / 2
LCM(421,686,800) = 115522400
