Given numbers are 263,731,790,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 263,731,790,645 is 455639610.
Find LCM of 263,731,790,645 with Prime Factorization
| 5 | 263, 731, 790, 645 |
| 43 | 263, 731, 158, 129 |
| 263, 17, 158, 3 |
Multiply the prime numbers at the bottom and the left side.
5 x 43 x 263 x 17 x 158 x 3 = 455639610
Therefore, the lowest common multiple of 263,731,790,645 is 455639610.
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.
263 x 731 x 790 x 645 = 97962516150
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.
263 : 1, 263
731 : 1, 17, 43, 731
790 : 1, 2, 5, 10, 79, 158, 395, 790
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,731,790,645, is 1.
Now, the common factors can be found like this.
263:263
731:17x 43
790:2x 5x 79
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 43 = 215
Therefore, the value for common factors is 215.
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 = 97962516150/(1x215)
LCM = 97962516150/215
LCM = 455639610
Thus, we can understand that the LCM of 263,731,790,645 is 455639610.
