Greatest Common Factor
We found the factors 37,73,84,12 . The biggest common factor number is the GCF number.
So the greatest common factor 37,73,84,12 is 1.
Lets's calculate LCM of 21,60,27,54
2 | 21, 60, 27, 54 |
3 | 21, 30, 27, 27 |
3 | 7, 10, 9, 9 |
3 | 7, 10, 3, 3 |
7, 10, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 7 x 10 x 1 x 1 = 3780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3780
Therefore, the GCF of Fractions 37/21,73/60,84/27,12/54 is 1/3780
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 21,60,27,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,60,27,54) = 3
common factors(in case of two or more numbers have common factors) = 162
GCF(21,60,27,54) x common factors =3 x 162 = 486
LCM(21,60,27,54) = ( 21 × 60 × 27 × 54 ) / 486
LCM(21,60,27,54) = 1837080 / 486
LCM(21,60,27,54) = 3780
