Greatest Common Factor
We found the factors 4689,3817 . The biggest common factor number is the GCF number.
So the greatest common factor 4689,3817 is 1.
Lets's calculate LCM of 354,420
2 | 354, 420 |
3 | 177, 210 |
59, 70 |
∴ So the LCM of the given numbers is 2 x 3 x 59 x 70 = 24780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24780
Therefore, the GCF of Fractions 4689/354,3817/420 is 1/24780
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 354,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(354,420) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(354,420) x common factors =6 x 1 = 6
LCM(354,420) = ( 354 × 420 ) / 6
LCM(354,420) = 148680 / 6
LCM(354,420) = 24780
