Lets's calculate LCM of 418,342
2 | 418, 342 |
19 | 209, 171 |
11, 9 |
∴ So the LCM of the given numbers is 2 x 19 x 11 x 9 = 3762
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/3762
Therefore, the GCF of Fractions 455/418,1725/342 is 5/3762
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 418,342 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(418,342) = 38
common factors(in case of two or more numbers have common factors) = 1
GCF(418,342) x common factors =38 x 1 = 38
LCM(418,342) = ( 418 × 342 ) / 38
LCM(418,342) = 142956 / 38
LCM(418,342) = 3762
