Lets's calculate LCM of 256,628
2 | 256, 628 |
2 | 128, 314 |
64, 157 |
∴ So the LCM of the given numbers is 2 x 2 x 64 x 157 = 40192
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 49/40192
Therefore, the GCF of Fractions 147/256,343/628 is 49/40192
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 256,628 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(256,628) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(256,628) x common factors =4 x 1 = 4
LCM(256,628) = ( 256 × 628 ) / 4
LCM(256,628) = 160768 / 4
LCM(256,628) = 40192
