The LCM of 630,845,507,768 is 13628160.
Find LCM of 630,845,507,768 with Prime Factorization
| 2 | 630, 845, 507, 768 |
| 3 | 315, 845, 507, 384 |
| 5 | 105, 845, 169, 128 |
| 13 | 21, 169, 169, 128 |
| 13 | 21, 13, 13, 128 |
| 21, 1, 1, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 13 x 21 x 1 x 1 x 128 = 13628160
Therefore, the lowest common multiple of 630,845,507,768 is 13628160.
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.
630 x 845 x 507 x 768 = 207284313600
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
845 : 1, 5, 13, 65, 169, 845
507 : 1, 3, 13, 39, 169, 507
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,845,507,768, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
845:5x 13x 13
507:3x 13x 13
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3x 5x 13x 13 = 15210
Therefore, the value for common factors is 15210.
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 = 207284313600/(1x15210)
LCM = 207284313600/15210
LCM = 13628160
Thus, we can understand that the LCM of 630,845,507,768 is 13628160.
