Given numbers are 353,731,690,645,933
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 353,731,690,645,933 is 55373447370.
Find LCM of 353,731,690,645,933 with Prime Factorization
| 3 | 353, 731, 690, 645, 933 |
| 5 | 353, 731, 230, 215, 311 |
| 43 | 353, 731, 46, 43, 311 |
| 353, 17, 46, 1, 311 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 353 x 17 x 46 x 1 x 311 = 55373447370
Therefore, the lowest common multiple of 353,731,690,645,933 is 55373447370.
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.
353 x 731 x 690 x 645 x 933 = 107147620660950
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.
353 : 1, 353
731 : 1, 17, 43, 731
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
645 : 1, 3, 5, 15, 43, 129, 215, 645
933 : 1, 3, 311, 933
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 353,731,690,645,933, is 1.
Now, the common factors can be found like this.
353:353
731:17x 43
690:2x 3x 5x 23
645:3x 5x 43
933:3x 311
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 43 = 1935
Therefore, the value for common factors is 1935.
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 = 107147620660950/(1x1935)
LCM = 107147620660950/1935
LCM = 55373447370
Thus, we can understand that the LCM of 353,731,690,645,933 is 55373447370.
