Given numbers are 400,844,946,790,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,844,946,790,731 is 53614171600.
Find LCM of 400,844,946,790,731 with Prime Factorization
| 2 | 400, 844, 946, 790, 731 |
| 2 | 200, 422, 473, 395, 731 |
| 5 | 100, 211, 473, 395, 731 |
| 43 | 20, 211, 473, 79, 731 |
| 20, 211, 11, 79, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 20 x 211 x 11 x 79 x 17 = 53614171600
Therefore, the lowest common multiple of 400,844,946,790,731 is 53614171600.
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.
400 x 844 x 946 x 790 x 731 = 184432750304000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
844 : 1, 2, 4, 211, 422, 844
946 : 1, 2, 11, 22, 43, 86, 473, 946
790 : 1, 2, 5, 10, 79, 158, 395, 790
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,844,946,790,731, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
844:2x 2x 211
946:2x 11x 43
790:2x 5x 79
731:17x 43
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 2x 2x 5x 43 = 3440
Therefore, the value for common factors is 3440.
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 = 184432750304000/(1x3440)
LCM = 184432750304000/3440
LCM = 53614171600
Thus, we can understand that the LCM of 400,844,946,790,731 is 53614171600.
