Given numbers are 105,380,399,469
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,380,399,469 is 534660.
Find LCM of 105,380,399,469 with Prime Factorization
| 3 | 105, 380, 399, 469 |
| 5 | 35, 380, 133, 469 |
| 7 | 7, 76, 133, 469 |
| 19 | 1, 76, 19, 67 |
| 1, 4, 1, 67 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 19 x 1 x 4 x 1 x 67 = 534660
Therefore, the lowest common multiple of 105,380,399,469 is 534660.
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.
105 x 380 x 399 x 469 = 7466526900
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
399 : 1, 3, 7, 19, 21, 57, 133, 399
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,380,399,469, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
380:2x 2x 5x 19
399:3x 7x 19
469:7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 7x 19 = 13965
Therefore, the value for common factors is 13965.
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 = 7466526900/(1x13965)
LCM = 7466526900/13965
LCM = 534660
Thus, we can understand that the LCM of 105,380,399,469 is 534660.
