Given numbers are 718,580,391,406,887
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,580,391,406,887 is 505499650180.
Find LCM of 718,580,391,406,887 with Prime Factorization
| 2 | 718, 580, 391, 406, 887 |
| 29 | 359, 290, 391, 203, 887 |
| 359, 10, 391, 7, 887 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 359 x 10 x 391 x 7 x 887 = 505499650180
Therefore, the lowest common multiple of 718,580,391,406,887 is 505499650180.
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.
718 x 580 x 391 x 406 x 887 = 58637959420880
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.
718 : 1, 2, 359, 718
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
391 : 1, 17, 23, 391
406 : 1, 2, 7, 14, 29, 58, 203, 406
887 : 1, 887
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,580,391,406,887, is 1.
Now, the common factors can be found like this.
718:2x 359
580:2x 2x 5x 29
391:17x 23
406:2x 7x 29
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 29 = 116
Therefore, the value for common factors is 116.
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 = 58637959420880/(1x116)
LCM = 58637959420880/116
LCM = 505499650180
Thus, we can understand that the LCM of 718,580,391,406,887 is 505499650180.
