Greatest Common Factor
We found the factors 720,956 . The biggest common factor number is the GCF number.
So the greatest common factor 720,956 is 4.
Lets's calculate LCM of 147,474
3 | 147, 474 |
49, 158 |
∴ So the LCM of the given numbers is 3 x 49 x 158 = 23226
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/23226
Therefore, the GCF of Fractions 720/147,956/474 is 4/23226
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 147,474 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(147,474) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(147,474) x common factors =3 x 1 = 3
LCM(147,474) = ( 147 × 474 ) / 3
LCM(147,474) = 69678 / 3
LCM(147,474) = 23226
