Given numbers are 759,451,815,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,451,815,861 is 177533895.
Find LCM of 759,451,815,861 with Prime Factorization
| 3 | 759, 451, 815, 861 |
| 11 | 253, 451, 815, 287 |
| 41 | 23, 41, 815, 287 |
| 23, 1, 815, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 41 x 23 x 1 x 815 x 7 = 177533895
Therefore, the lowest common multiple of 759,451,815,861 is 177533895.
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.
759 x 451 x 815 x 861 = 240203359935
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
451 : 1, 11, 41, 451
815 : 1, 5, 163, 815
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,451,815,861, is 1.
Now, the common factors can be found like this.
759:3x 11x 23
451:11x 41
815:5x 163
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 41 = 1353
Therefore, the value for common factors is 1353.
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 = 240203359935/(1x1353)
LCM = 240203359935/1353
LCM = 177533895
Thus, we can understand that the LCM of 759,451,815,861 is 177533895.
