Given numbers are 143,858,643,991,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,858,643,991,705 is 128481257190.
Find LCM of 143,858,643,991,705 with Prime Factorization
| 3 | 143, 858, 643, 991, 705 |
| 11 | 143, 286, 643, 991, 235 |
| 13 | 13, 26, 643, 991, 235 |
| 1, 2, 643, 991, 235 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 1 x 2 x 643 x 991 x 235 = 128481257190
Therefore, the lowest common multiple of 143,858,643,991,705 is 128481257190.
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.
143 x 858 x 643 x 991 x 705 = 55118459334510
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.
143 : 1, 11, 13, 143
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
643 : 1, 643
991 : 1, 991
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,858,643,991,705, is 1.
Now, the common factors can be found like this.
143:11x 13
858:2x 3x 11x 13
643:643
991:991
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 13 = 429
Therefore, the value for common factors is 429.
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 = 55118459334510/(1x429)
LCM = 55118459334510/429
LCM = 128481257190
Thus, we can understand that the LCM of 143,858,643,991,705 is 128481257190.
