Greatest Common Factor
We found the factors 140,580 . The biggest common factor number is the GCF number.
So the greatest common factor 140,580 is 20.
Lets's calculate LCM of 12,7458
2 | 12, 7458 |
3 | 6, 3729 |
2, 1243 |
∴ So the LCM of the given numbers is 2 x 3 x 2 x 1243 = 14916
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/14916
Therefore, the GCF of Fractions 140/12,580/7458 is 20/14916
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 12,7458 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,7458) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(12,7458) x common factors =6 x 1 = 6
LCM(12,7458) = ( 12 × 7458 ) / 6
LCM(12,7458) = 89496 / 6
LCM(12,7458) = 14916
