So the greatest common factor 985,252 is 1.
Lets's calculate LCM of 424,428
2 | 424, 428 |
2 | 212, 214 |
106, 107 |
∴ So the LCM of the given numbers is 2 x 2 x 106 x 107 = 45368
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/45368
Therefore, the GCF of Fractions 985/424,252/428 is 1/45368
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 424,428 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(424,428) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(424,428) x common factors =4 x 1 = 4
LCM(424,428) = ( 424 × 428 ) / 4
LCM(424,428) = 181472 / 4
LCM(424,428) = 45368
