Given numbers are 859,840,936,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 859,840,936,678 is 3179914920.
Find LCM of 859,840,936,678 with Prime Factorization
| 2 | 859, 840, 936, 678 |
| 2 | 859, 420, 468, 339 |
| 2 | 859, 210, 234, 339 |
| 3 | 859, 105, 117, 339 |
| 859, 35, 39, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 859 x 35 x 39 x 113 = 3179914920
Therefore, the lowest common multiple of 859,840,936,678 is 3179914920.
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.
859 x 840 x 936 x 678 = 457907748480
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.
859 : 1, 859
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,840,936,678, is 1.
Now, the common factors can be found like this.
859:859
840:2x 2x 2x 3x 5x 7
936:2x 2x 2x 3x 3x 13
678:2x 3x 113
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 457907748480/(1x144)
LCM = 457907748480/144
LCM = 3179914920
Thus, we can understand that the LCM of 859,840,936,678 is 3179914920.
