Greatest Common Factor
We found the factors 157,128 . The biggest common factor number is the GCF number.
So the greatest common factor 157,128 is 1.
Lets's calculate LCM of 28,512
2 | 28, 512 |
2 | 14, 256 |
7, 128 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 128 = 3584
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3584
Therefore, the GCF of Fractions 157/28,128/512 is 1/3584
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 28,512 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,512) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(28,512) x common factors =4 x 1 = 4
LCM(28,512) = ( 28 × 512 ) / 4
LCM(28,512) = 14336 / 4
LCM(28,512) = 3584
