We found the factors 671,457 . The biggest common factor number is the GCF number.
So the greatest common factor 671,457 is 1.
Lets's calculate LCM of 564,168
2 | 564, 168 |
2 | 282, 84 |
3 | 141, 42 |
47, 14 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 47 x 14 = 7896
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7896
Therefore, the GCF of Fractions 671/564,457/168 is 1/7896
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 564,168 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(564,168) = 12
common factors(in case of two or more numbers have common factors) = 1
GCF(564,168) x common factors =12 x 1 = 12
LCM(564,168) = ( 564 × 168 ) / 12
LCM(564,168) = 94752 / 12
LCM(564,168) = 7896
