Given numbers are 105,399,754,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,399,754,609 is 1504230.
Find LCM of 105,399,754,609 with Prime Factorization
| 3 | 105, 399, 754, 609 |
| 7 | 35, 133, 754, 203 |
| 29 | 5, 19, 754, 29 |
| 5, 19, 26, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 29 x 5 x 19 x 26 x 1 = 1504230
Therefore, the lowest common multiple of 105,399,754,609 is 1504230.
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 399 x 754 x 609 = 19237597470
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
399 : 1, 3, 7, 19, 21, 57, 133, 399
754 : 1, 2, 13, 26, 29, 58, 377, 754
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,399,754,609, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
399:3x 7x 19
754:2x 13x 29
609:3x 7x 29
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 7x 7x 29 = 12789
Therefore, the value for common factors is 12789.
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 = 19237597470/(1x12789)
LCM = 19237597470/12789
LCM = 1504230
Thus, we can understand that the LCM of 105,399,754,609 is 1504230.
