Given numbers are 415,989,519,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 415,989,519,920 is 1704126120.
Find LCM of 415,989,519,920 with Prime Factorization
| 5 | 415, 989, 519, 920 |
| 23 | 83, 989, 519, 184 |
| 83, 43, 519, 8 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 83 x 43 x 519 x 8 = 1704126120
Therefore, the lowest common multiple of 415,989,519,920 is 1704126120.
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.
415 x 989 x 519 x 920 = 195974503800
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.
415 : 1, 5, 83, 415
989 : 1, 23, 43, 989
519 : 1, 3, 173, 519
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,989,519,920, is 1.
Now, the common factors can be found like this.
415:5x 83
989:23x 43
519:3x 173
920:2x 2x 2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 195974503800/(1x115)
LCM = 195974503800/115
LCM = 1704126120
Thus, we can understand that the LCM of 415,989,519,920 is 1704126120.
