1,2,4,8,16,211,422,844,1688,3376
Greatest Common Factor
We found the factors 165,3376 . The biggest common factor number is the GCF number.
So the greatest common factor 165,3376 is 1.
Lets's calculate LCM of 390,540
2 | 390, 540 |
3 | 195, 270 |
5 | 65, 90 |
13, 18 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 13 x 18 = 7020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7020
Therefore, the GCF of Fractions 165/390,3376/540 is 1/7020
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 390,540 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,540) = 30
common factors(in case of two or more numbers have common factors) = 1
GCF(390,540) x common factors =30 x 1 = 30
LCM(390,540) = ( 390 × 540 ) / 30
LCM(390,540) = 210600 / 30
LCM(390,540) = 7020
