So the greatest common factor 156,624 is 156.
Lets's calculate LCM of 64,512
2 | 64, 512 |
2 | 32, 256 |
2 | 16, 128 |
2 | 8, 64 |
2 | 4, 32 |
2 | 2, 16 |
1, 8 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 2 x 1 x 8 = 512
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 156/512
Therefore, the GCF of Fractions 156/64,624/512 is 156/512
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 64,512 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,512) = 64
common factors(in case of two or more numbers have common factors) = 1
GCF(64,512) x common factors =64 x 1 = 64
LCM(64,512) = ( 64 × 512 ) / 64
LCM(64,512) = 32768 / 64
LCM(64,512) = 512
