Find LCM of 855,452,974,858,143 with Prime Factorization
| 2 | 855, 452, 974, 858, 143 |
| 3 | 855, 226, 487, 429, 143 |
| 11 | 285, 226, 487, 143, 143 |
| 13 | 285, 226, 487, 13, 13 |
| 285, 226, 487, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 285 x 226 x 487 x 1 x 1 = 26913460860
Therefore, the lowest common multiple of 855,452,974,858,143 is 26913460860.
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.
855 x 452 x 974 x 858 x 143 = 46183498835760
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
452 : 1, 2, 4, 113, 226, 452
974 : 1, 2, 487, 974
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,452,974,858,143, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
452:2x 2x 113
974:2x 487
858:2x 3x 11x 13
143:11x 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 11x 13 = 1716
Therefore, the value for common factors is 1716.
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 = 46183498835760/(1x1716)
LCM = 46183498835760/1716
LCM = 26913460860
Thus, we can understand that the LCM of 855,452,974,858,143 is 26913460860.
