So the greatest common factor 206,1442 is 206.
Lets's calculate LCM of 128,4712
2 | 128, 4712 |
2 | 64, 2356 |
2 | 32, 1178 |
16, 589 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 16 x 589 = 75392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 206/75392
Therefore, the GCF of Fractions 206/128,1442/4712 is 206/75392
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 128,4712 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(128,4712) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(128,4712) x common factors =8 x 1 = 8
LCM(128,4712) = ( 128 × 4712 ) / 8
LCM(128,4712) = 603136 / 8
LCM(128,4712) = 75392
