Given numbers are 387,609,899,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,609,899,518 is 180218934.
Find LCM of 387,609,899,518 with Prime Factorization
| 3 | 387, 609, 899, 518 |
| 7 | 129, 203, 899, 518 |
| 29 | 129, 29, 899, 74 |
| 129, 1, 31, 74 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 29 x 129 x 1 x 31 x 74 = 180218934
Therefore, the lowest common multiple of 387,609,899,518 is 180218934.
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.
387 x 609 x 899 x 518 = 109753330806
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.
387 : 1, 3, 9, 43, 129, 387
609 : 1, 3, 7, 21, 29, 87, 203, 609
899 : 1, 29, 31, 899
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,609,899,518, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
609:3x 7x 29
899:29x 31
518:2x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 29 = 609
Therefore, the value for common factors is 609.
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 = 109753330806/(1x609)
LCM = 109753330806/609
LCM = 180218934
Thus, we can understand that the LCM of 387,609,899,518 is 180218934.
