So the greatest common factor 361,672 is 1.
Lets's calculate LCM of 390,382
2 | 390, 382 |
195, 191 |
∴ So the LCM of the given numbers is 2 x 195 x 191 = 74490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/74490
Therefore, the GCF of Fractions 361/390,672/382 is 1/74490
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 390,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,382) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(390,382) x common factors =2 x 1 = 2
LCM(390,382) = ( 390 × 382 ) / 2
LCM(390,382) = 148980 / 2
LCM(390,382) = 74490
