Find LCM of 814,387,286,324,715 with Prime Factorization
| 2 | 814, 387, 286, 324, 715 |
| 3 | 407, 387, 143, 162, 715 |
| 3 | 407, 129, 143, 54, 715 |
| 11 | 407, 43, 143, 18, 715 |
| 13 | 37, 43, 13, 18, 65 |
| 37, 43, 1, 18, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 13 x 37 x 43 x 1 x 18 x 5 = 368571060
Therefore, the lowest common multiple of 814,387,286,324,715 is 368571060.
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.
814 x 387 x 286 x 324 x 715 = 20871441985680
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
387 : 1, 3, 9, 43, 129, 387
286 : 1, 2, 11, 13, 22, 26, 143, 286
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,387,286,324,715, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
387:3x 3x 43
286:2x 11x 13
324:2x 2x 3x 3x 3x 3
715:5x 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 11x 11x 13 = 56628
Therefore, the value for common factors is 56628.
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 = 20871441985680/(1x56628)
LCM = 20871441985680/56628
LCM = 368571060
Thus, we can understand that the LCM of 814,387,286,324,715 is 368571060.
