:1,2,3,4,6,12
Now, list down the factors of 545
:1,5,109,545
Now, list down the factors of 709
:1,709
Greatest Common Factor
We found the factors 12,545,709 . The biggest common factor number is the GCF number.
So the greatest common factor 12,545,709 is 1.
Lets's calculate LCM of 63,51,486
3 | 63, 51, 486 |
3 | 21, 17, 162 |
7, 17, 54 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 17 x 54 = 57834
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/57834
Therefore, the GCF of Fractions 12/63,545/51,709/486 is 1/57834
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 63,51,486 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,51,486) = 3
common factors(in case of two or more numbers have common factors) = 9
GCF(63,51,486) x common factors =3 x 9 = 27
LCM(63,51,486) = ( 63 × 51 × 486 ) / 27
LCM(63,51,486) = 1561518 / 27
LCM(63,51,486) = 57834
