Given numbers are 304,432,920,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 304,432,920,545 is 102887280.
Find LCM of 304,432,920,545 with Prime Factorization
| 2 | 304, 432, 920, 545 |
| 2 | 152, 216, 460, 545 |
| 2 | 76, 108, 230, 545 |
| 2 | 38, 54, 115, 545 |
| 5 | 19, 27, 115, 545 |
| 19, 27, 23, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 19 x 27 x 23 x 109 = 102887280
Therefore, the lowest common multiple of 304,432,920,545 is 102887280.
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.
304 x 432 x 920 x 545 = 65847859200
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.
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,432,920,545, is 1.
Now, the common factors can be found like this.
304:2x 2x 2x 2x 19
432:2x 2x 2x 2x 3x 3x 3
920:2x 2x 2x 5x 23
545:5x 109
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 5 = 640
Therefore, the value for common factors is 640.
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 = 65847859200/(1x640)
LCM = 65847859200/640
LCM = 102887280
Thus, we can understand that the LCM of 304,432,920,545 is 102887280.
