Given numbers are 409,818,654,366,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,818,654,366,878 is 7163007594.
Find LCM of 409,818,654,366,878 with Prime Factorization
| 2 | 409, 818, 654, 366, 878 |
| 3 | 409, 409, 327, 183, 439 |
| 409 | 409, 409, 109, 61, 439 |
| 1, 1, 109, 61, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 409 x 1 x 1 x 109 x 61 x 439 = 7163007594
Therefore, the lowest common multiple of 409,818,654,366,878 is 7163007594.
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.
409 x 818 x 654 x 366 x 878 = 70312082542704
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.
409 : 1, 409
818 : 1, 2, 409, 818
654 : 1, 2, 3, 6, 109, 218, 327, 654
366 : 1, 2, 3, 6, 61, 122, 183, 366
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,818,654,366,878, is 1.
Now, the common factors can be found like this.
409:409
818:2x 409
654:2x 3x 109
366:2x 3x 61
878:2x 439
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 409 = 9816
Therefore, the value for common factors is 9816.
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 = 70312082542704/(1x9816)
LCM = 70312082542704/9816
LCM = 7163007594
Thus, we can understand that the LCM of 409,818,654,366,878 is 7163007594.
