Given numbers are 119,203,408,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 119,203,408,638 is 911064.
Find LCM of 119,203,408,638 with Prime Factorization
| 2 | 119, 203, 408, 638 |
| 7 | 119, 203, 204, 319 |
| 17 | 17, 29, 204, 319 |
| 29 | 1, 29, 12, 319 |
| 1, 1, 12, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 29 x 1 x 1 x 12 x 11 = 911064
Therefore, the lowest common multiple of 119,203,408,638 is 911064.
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.
119 x 203 x 408 x 638 = 6288163728
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.
119 : 1, 7, 17, 119
203 : 1, 7, 29, 203
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
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 119,203,408,638, is 1.
Now, the common factors can be found like this.
119:7x 17
203:7x 29
408:2x 2x 2x 3x 17
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 7x 17x 29 = 6902
Therefore, the value for common factors is 6902.
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 = 6288163728/(1x6902)
LCM = 6288163728/6902
LCM = 911064
Thus, we can understand that the LCM of 119,203,408,638 is 911064.
