Given numbers are 834,453,840,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,453,840,990 is 581815080.
Find LCM of 834,453,840,990 with Prime Factorization
| 2 | 834, 453, 840, 990 |
| 3 | 417, 453, 420, 495 |
| 5 | 139, 151, 140, 165 |
| 139, 151, 28, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 139 x 151 x 28 x 33 = 581815080
Therefore, the lowest common multiple of 834,453,840,990 is 581815080.
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.
834 x 453 x 840 x 990 = 314180143200
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
453 : 1, 3, 151, 453
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,453,840,990, is 3.
Now, the common factors can be found like this.
834:2x 3x 139
453:3x 151
840:2x 2x 2x 3x 5x 7
990:2x 3x 3x 5x 11
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 314180143200/(3x180)
LCM = 314180143200/540
LCM = 581815080
Thus, we can understand that the LCM of 834,453,840,990 is 581815080.
