So the greatest common factor 427,945 is 7.
Lets's calculate LCM of 904,988
2 | 904, 988 |
2 | 452, 494 |
226, 247 |
∴ So the LCM of the given numbers is 2 x 2 x 226 x 247 = 223288
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/223288
Therefore, the GCF of Fractions 427/904,945/988 is 7/223288
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 904,988 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(904,988) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(904,988) x common factors =4 x 1 = 4
LCM(904,988) = ( 904 × 988 ) / 4
LCM(904,988) = 893152 / 4
LCM(904,988) = 223288
