So the greatest common factor 21,266,846 is 1.
Lets's calculate LCM of 291,872,260
2 | 291, 872, 260 |
2 | 291, 436, 130 |
291, 218, 65 |
∴ So the LCM of the given numbers is 2 x 2 x 291 x 218 x 65 = 16493880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16493880
Therefore, the GCF of Fractions 21/291,266/872,846/260 is 1/16493880
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 291,872,260 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(291,872,260) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(291,872,260) x common factors =1 x 4 = 4
LCM(291,872,260) = ( 291 × 872 × 260 ) / 4
LCM(291,872,260) = 65975520 / 4
LCM(291,872,260) = 16493880
