Find LCM of 286,903,627,391,780 with Prime Factorization
| 2 | 286, 903, 627, 391, 780 |
| 3 | 143, 903, 627, 391, 390 |
| 11 | 143, 301, 209, 391, 130 |
| 13 | 13, 301, 19, 391, 130 |
| 1, 301, 19, 391, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 1 x 301 x 19 x 391 x 10 = 19185986820
Therefore, the lowest common multiple of 286,903,627,391,780 is 19185986820.
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.
286 x 903 x 627 x 391 x 780 = 49384730074680
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
903 : 1, 3, 7, 21, 43, 129, 301, 903
627 : 1, 3, 11, 19, 33, 57, 209, 627
391 : 1, 17, 23, 391
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,903,627,391,780, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
903:3x 7x 43
627:3x 11x 19
391:17x 23
780:2x 2x 3x 5x 13
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 11x 13 = 2574
Therefore, the value for common factors is 2574.
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 = 49384730074680/(1x2574)
LCM = 49384730074680/2574
LCM = 19185986820
Thus, we can understand that the LCM of 286,903,627,391,780 is 19185986820.
