So the greatest common factor 830,312 is 2.
Lets's calculate LCM of 256,248
2 | 256, 248 |
2 | 128, 124 |
2 | 64, 62 |
32, 31 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 32 x 31 = 7936
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/7936
Therefore, the GCF of Fractions 830/256,312/248 is 2/7936
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 256,248 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(256,248) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(256,248) x common factors =8 x 1 = 8
LCM(256,248) = ( 256 × 248 ) / 8
LCM(256,248) = 63488 / 8
LCM(256,248) = 7936
