Find LCM of 468,285,480,763,490 with Prime Factorization
| 2 | 468, 285, 480, 763, 490 |
| 2 | 234, 285, 240, 763, 245 |
| 3 | 117, 285, 120, 763, 245 |
| 5 | 39, 95, 40, 763, 245 |
| 7 | 39, 19, 8, 763, 49 |
| 39, 19, 8, 109, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 39 x 19 x 8 x 109 x 7 = 1899686880
Therefore, the lowest common multiple of 468,285,480,763,490 is 1899686880.
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.
468 x 285 x 480 x 763 x 490 = 23936054688000
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
285 : 1, 3, 5, 15, 19, 57, 95, 285
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
763 : 1, 7, 109, 763
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,285,480,763,490, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
285:3x 5x 19
480:2x 2x 2x 2x 2x 3x 5
763:7x 109
490:2x 5x 7x 7
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 3x 3x 5x 5x 7 = 12600
Therefore, the value for common factors is 12600.
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 = 23936054688000/(1x12600)
LCM = 23936054688000/12600
LCM = 1899686880
Thus, we can understand that the LCM of 468,285,480,763,490 is 1899686880.
