Given numbers are 558,430,138,642,887
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,430,138,642,887 is 261883352790.
Find LCM of 558,430,138,642,887 with Prime Factorization
| 2 | 558, 430, 138, 642, 887 |
| 3 | 279, 215, 69, 321, 887 |
| 93, 215, 23, 107, 887 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 93 x 215 x 23 x 107 x 887 = 261883352790
Therefore, the lowest common multiple of 558,430,138,642,887 is 261883352790.
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 430 x 138 x 642 x 887 = 18855601400880
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
430 : 1, 2, 5, 10, 43, 86, 215, 430
138 : 1, 2, 3, 6, 23, 46, 69, 138
642 : 1, 2, 3, 6, 107, 214, 321, 642
887 : 1, 887
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,430,138,642,887, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
430:2x 5x 43
138:2x 3x 23
642:2x 3x 107
887:887
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 18855601400880/(1x72)
LCM = 18855601400880/72
LCM = 261883352790
Thus, we can understand that the LCM of 558,430,138,642,887 is 261883352790.
