:1,2,107,214
Now, list down the factors of 441
:1,3,7,9,21,49,63,147,441
Greatest Common Factor
We found the factors 13,214,441 . The biggest common factor number is the GCF number.
So the greatest common factor 13,214,441 is 1.
Lets's calculate LCM of 45,12,642
2 | 45, 12, 642 |
3 | 45, 6, 321 |
15, 2, 107 |
∴ So the LCM of the given numbers is 2 x 3 x 15 x 2 x 107 = 19260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19260
Therefore, the GCF of Fractions 13/45,214/12,441/642 is 1/19260
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 45,12,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,12,642) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(45,12,642) x common factors =3 x 6 = 18
LCM(45,12,642) = ( 45 × 12 × 642 ) / 18
LCM(45,12,642) = 346680 / 18
LCM(45,12,642) = 19260
