Given numbers are 840,846,913,684,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,846,913,684,828 is 47255309640.
Find LCM of 840,846,913,684,828 with Prime Factorization
| 2 | 840, 846, 913, 684, 828 |
| 2 | 420, 423, 913, 342, 414 |
| 3 | 210, 423, 913, 171, 207 |
| 3 | 70, 141, 913, 57, 69 |
| 70, 47, 913, 19, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 70 x 47 x 913 x 19 x 23 = 47255309640
Therefore, the lowest common multiple of 840,846,913,684,828 is 47255309640.
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.
840 x 846 x 913 x 684 x 828 = 367457287760640
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.
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
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
913 : 1, 11, 83, 913
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,846,913,684,828, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
846:2x 3x 3x 47
913:11x 83
684:2x 2x 3x 3x 19
828:2x 2x 3x 3x 23
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 2x 3x 3x 3x 3x 3 = 7776
Therefore, the value for common factors is 7776.
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 = 367457287760640/(1x7776)
LCM = 367457287760640/7776
LCM = 47255309640
Thus, we can understand that the LCM of 840,846,913,684,828 is 47255309640.
