So the greatest common factor 901,170 is 17.
Lets's calculate LCM of 138,369
3 | 138, 369 |
46, 123 |
∴ So the LCM of the given numbers is 3 x 46 x 123 = 16974
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 17/16974
Therefore, the GCF of Fractions 901/138,170/369 is 17/16974
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 138,369 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(138,369) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(138,369) x common factors =3 x 1 = 3
LCM(138,369) = ( 138 × 369 ) / 3
LCM(138,369) = 50922 / 3
LCM(138,369) = 16974
