Given numbers are 288,311,415,688,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 288,311,415,688,400 is 7991704800.
Find LCM of 288,311,415,688,400 with Prime Factorization
| 2 | 288, 311, 415, 688, 400 |
| 2 | 144, 311, 415, 344, 200 |
| 2 | 72, 311, 415, 172, 100 |
| 2 | 36, 311, 415, 86, 50 |
| 5 | 18, 311, 415, 43, 25 |
| 18, 311, 83, 43, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 18 x 311 x 83 x 43 x 5 = 7991704800
Therefore, the lowest common multiple of 288,311,415,688,400 is 7991704800.
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.
288 x 311 x 415 x 688 x 400 = 10229382144000
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.
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
311 : 1, 311
415 : 1, 5, 83, 415
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,311,415,688,400, is 1.
Now, the common factors can be found like this.
288:2x 2x 2x 2x 2x 3x 3
311:311
415:5x 83
688:2x 2x 2x 2x 43
400:2x 2x 2x 2x 5x 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 2x 2x 2x 2x 2x 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 10229382144000/(1x1280)
LCM = 10229382144000/1280
LCM = 7991704800
Thus, we can understand that the LCM of 288,311,415,688,400 is 7991704800.
