The LCM of 286,887,816,643,442 is 66551950608.
Find LCM of 286,887,816,643,442 with Prime Factorization
| 2 | 286, 887, 816, 643, 442 |
| 13 | 143, 887, 408, 643, 221 |
| 17 | 11, 887, 408, 643, 17 |
| 11, 887, 24, 643, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 11 x 887 x 24 x 643 x 1 = 66551950608
Therefore, the lowest common multiple of 286,887,816,643,442 is 66551950608.
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 887 x 816 x 643 x 442 = 58831924337472
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
887 : 1, 887
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
643 : 1, 643
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,887,816,643,442, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
887:887
816:2x 2x 2x 2x 3x 17
643:643
442:2x 13x 17
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 13x 17 = 884
Therefore, the value for common factors is 884.
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 = 58831924337472/(1x884)
LCM = 58831924337472/884
LCM = 66551950608
Thus, we can understand that the LCM of 286,887,816,643,442 is 66551950608.
