Given numbers are 878,338,804,678,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 878,338,804,678,861 is 1934495010084.
Find LCM of 878,338,804,678,861 with Prime Factorization
| 2 | 878, 338, 804, 678, 861 |
| 3 | 439, 169, 402, 339, 861 |
| 439, 169, 134, 113, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 439 x 169 x 134 x 113 x 287 = 1934495010084
Therefore, the lowest common multiple of 878,338,804,678,861 is 1934495010084.
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.
878 x 338 x 804 x 678 x 861 = 139283640726048
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.
878 : 1, 2, 439, 878
338 : 1, 2, 13, 26, 169, 338
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
678 : 1, 2, 3, 6, 113, 226, 339, 678
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 878,338,804,678,861, is 1.
Now, the common factors can be found like this.
878:2x 439
338:2x 13x 13
804:2x 2x 3x 67
678:2x 3x 113
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.
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 = 139283640726048/(1x72)
LCM = 139283640726048/72
LCM = 1934495010084
Thus, we can understand that the LCM of 878,338,804,678,861 is 1934495010084.
