Given numbers are 704,899,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 704,899,638 is 632896.
Find LCM of 704,899,638 with Prime Factorization
| 2 | 704, 899, 638 |
| 11 | 352, 899, 319 |
| 29 | 32, 899, 29 |
| 32, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 32 x 31 x 1 = 632896
Therefore, the lowest common multiple of 704,899,638 is 632896.
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.
704 x 899 x 638 = 403787648
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
899 : 1, 29, 31, 899
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,899,638, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
899:29x 31
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 29 = 638
Therefore, the value for common factors is 638.
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 = 403787648/(1x638)
LCM = 403787648/638
LCM = 632896
Thus, we can understand that the LCM of 704,899,638 is 632896.
