Greatest Common Factor
We found the factors 3210,4060 . The biggest common factor number is the GCF number.
So the greatest common factor 3210,4060 is 10.
Lets's calculate LCM of 512,124
2 | 512, 124 |
2 | 256, 62 |
128, 31 |
∴ So the LCM of the given numbers is 2 x 2 x 128 x 31 = 15872
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/15872
Therefore, the GCF of Fractions 3210/512,4060/124 is 10/15872
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 512,124 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(512,124) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(512,124) x common factors =4 x 1 = 4
LCM(512,124) = ( 512 × 124 ) / 4
LCM(512,124) = 63488 / 4
LCM(512,124) = 15872
