Greatest Common Factor
We found the factors 166,130,628 . The biggest common factor number is the GCF number.
So the greatest common factor 166,130,628 is 2.
Lets's calculate LCM of 30,93,21
3 | 30, 93, 21 |
10, 31, 7 |
∴ So the LCM of the given numbers is 3 x 10 x 31 x 7 = 6510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/6510
Therefore, the GCF of Fractions 166/30,130/93,628/21 is 2/6510
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 30,93,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,93,21) = 3
common factors(in case of two or more numbers have common factors) = 3
GCF(30,93,21) x common factors =3 x 3 = 9
LCM(30,93,21) = ( 30 × 93 × 21 ) / 9
LCM(30,93,21) = 58590 / 9
LCM(30,93,21) = 6510
