Given numbers are 323,273,646,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 323,273,646,240 is 7054320.
Find LCM of 323,273,646,240 with Prime Factorization
| 2 | 323, 273, 646, 240 |
| 3 | 323, 273, 323, 120 |
| 17 | 323, 91, 323, 40 |
| 19 | 19, 91, 19, 40 |
| 1, 91, 1, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 1 x 91 x 1 x 40 = 7054320
Therefore, the lowest common multiple of 323,273,646,240 is 7054320.
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.
323 x 273 x 646 x 240 = 13671272160
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.
323 : 1, 17, 19, 323
273 : 1, 3, 7, 13, 21, 39, 91, 273
646 : 1, 2, 17, 19, 34, 38, 323, 646
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,273,646,240, is 1.
Now, the common factors can be found like this.
323:17x 19
273:3x 7x 13
646:2x 17x 19
240:2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17x 19 = 1938
Therefore, the value for common factors is 1938.
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 = 13671272160/(1x1938)
LCM = 13671272160/1938
LCM = 7054320
Thus, we can understand that the LCM of 323,273,646,240 is 7054320.
