Given numbers are 558,675,876,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,675,876,390 is 79431300.
Find LCM of 558,675,876,390 with Prime Factorization
| 2 | 558, 675, 876, 390 |
| 3 | 279, 675, 438, 195 |
| 3 | 93, 225, 146, 65 |
| 5 | 31, 75, 146, 65 |
| 31, 15, 146, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 31 x 15 x 146 x 13 = 79431300
Therefore, the lowest common multiple of 558,675,876,390 is 79431300.
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.
558 x 675 x 876 x 390 = 128678706000
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,675,876,390, is 3.
Now, the common factors can be found like this.
558:2x 3x 3x 31
675:3x 3x 3x 5x 5
876:2x 2x 3x 73
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 128678706000/(3x540)
LCM = 128678706000/1620
LCM = 79431300
Thus, we can understand that the LCM of 558,675,876,390 is 79431300.
