So the greatest common factor 186,858 is 6.
Lets's calculate LCM of 256,158
2 | 256, 158 |
128, 79 |
∴ So the LCM of the given numbers is 2 x 128 x 79 = 20224
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/20224
Therefore, the GCF of Fractions 186/256,858/158 is 6/20224
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 256,158 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(256,158) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(256,158) x common factors =2 x 1 = 2
LCM(256,158) = ( 256 × 158 ) / 2
LCM(256,158) = 40448 / 2
LCM(256,158) = 20224
