Find LCM of 126,468,209,787,858 with Prime Factorization
| 2 | 126, 468, 209, 787, 858 |
| 3 | 63, 234, 209, 787, 429 |
| 3 | 21, 78, 209, 787, 143 |
| 11 | 7, 26, 209, 787, 143 |
| 13 | 7, 26, 19, 787, 13 |
| 7, 2, 19, 787, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 13 x 7 x 2 x 19 x 787 x 1 = 538846308
Therefore, the lowest common multiple of 126,468,209,787,858 is 538846308.
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.
126 x 468 x 209 x 787 x 858 = 8321942380752
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
209 : 1, 11, 19, 209
787 : 1, 787
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,468,209,787,858, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
468:2x 2x 3x 3x 13
209:11x 19
787:787
858:2x 3x 11x 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 2x 3x 3x 3x 11x 13 = 15444
Therefore, the value for common factors is 15444.
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 = 8321942380752/(1x15444)
LCM = 8321942380752/15444
LCM = 538846308
Thus, we can understand that the LCM of 126,468,209,787,858 is 538846308.
