The LCM of 270,195,621,909 is 8153730.
Find LCM of 270,195,621,909 with Prime Factorization
| 3 | 270, 195, 621, 909 |
| 3 | 90, 65, 207, 303 |
| 3 | 30, 65, 69, 101 |
| 5 | 10, 65, 23, 101 |
| 2, 13, 23, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 2 x 13 x 23 x 101 = 8153730
Therefore, the lowest common multiple of 270,195,621,909 is 8153730.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
270 x 195 x 621 x 909 = 29720345850
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
195 : 1, 3, 5, 13, 15, 39, 65, 195
621 : 1, 3, 9, 23, 27, 69, 207, 621
909 : 1, 3, 9, 101, 303, 909
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,195,621,909, is 3.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
195:3x 5x 13
621:3x 3x 3x 23
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 5 = 1215
Therefore, the value for common factors is 1215.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 29720345850/(3x1215)
LCM = 29720345850/3645
LCM = 8153730
Thus, we can understand that the LCM of 270,195,621,909 is 8153730.
