Given numbers are 866,840,579,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,840,579,648 is 1895344920.
Find LCM of 866,840,579,648 with Prime Factorization
| 2 | 866, 840, 579, 648 |
| 2 | 433, 420, 579, 324 |
| 2 | 433, 210, 579, 162 |
| 3 | 433, 105, 579, 81 |
| 433, 35, 193, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 433 x 35 x 193 x 27 = 1895344920
Therefore, the lowest common multiple of 866,840,579,648 is 1895344920.
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.
866 x 840 x 579 x 648 = 272929668480
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.
866 : 1, 2, 433, 866
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
579 : 1, 3, 193, 579
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,840,579,648, is 1.
Now, the common factors can be found like this.
866:2x 433
840:2x 2x 2x 3x 5x 7
579:3x 193
648:2x 2x 2x 3x 3x 3x 3
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 = 272929668480/(1x144)
LCM = 272929668480/144
LCM = 1895344920
Thus, we can understand that the LCM of 866,840,579,648 is 1895344920.
