Lets's calculate LCM of 128,558
2 | 128, 558 |
64, 279 |
∴ So the LCM of the given numbers is 2 x 64 x 279 = 35712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/35712
Therefore, the GCF of Fractions 988/128,142/558 is 2/35712
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 128,558 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,558) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(128,558) x common factors =2 x 1 = 2
LCM(128,558) = ( 128 × 558 ) / 2
LCM(128,558) = 71424 / 2
LCM(128,558) = 35712
