So the greatest common factor 457,3920 is 1.
Lets's calculate LCM of 338,222
2 | 338, 222 |
169, 111 |
∴ So the LCM of the given numbers is 2 x 169 x 111 = 37518
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/37518
Therefore, the GCF of Fractions 457/338,3920/222 is 1/37518
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 338,222 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(338,222) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(338,222) x common factors =2 x 1 = 2
LCM(338,222) = ( 338 × 222 ) / 2
LCM(338,222) = 75036 / 2
LCM(338,222) = 37518
