:1,3,5,15,499,1497,2495,7485
Now, list down the factors of 8472
:1,2,3,4,6,8,12,24,353,706,1059,1412,2118,2824,4236,8472
Greatest Common Factor
We found the factors 7485,8472 . The biggest common factor number is the GCF number.
So the greatest common factor 7485,8472 is 3.
Lets's calculate LCM of 420,4551
3 | 420, 4551 |
140, 1517 |
∴ So the LCM of the given numbers is 3 x 140 x 1517 = 637140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/637140
Therefore, the GCF of Fractions 7485/420,8472/4551 is 3/637140
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 420,4551 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,4551) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(420,4551) x common factors =3 x 1 = 3
LCM(420,4551) = ( 420 × 4551 ) / 3
LCM(420,4551) = 1911420 / 3
LCM(420,4551) = 637140
