Given numbers are 834,820,732,105,723
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,820,732,105,723 is 35188019580.
Find LCM of 834,820,732,105,723 with Prime Factorization
| 2 | 834, 820, 732, 105, 723 |
| 2 | 417, 410, 366, 105, 723 |
| 3 | 417, 205, 183, 105, 723 |
| 5 | 139, 205, 61, 35, 241 |
| 139, 41, 61, 7, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 139 x 41 x 61 x 7 x 241 = 35188019580
Therefore, the lowest common multiple of 834,820,732,105,723 is 35188019580.
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 820 x 732 x 105 x 723 = 38003061146400
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
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
105 : 1, 3, 5, 7, 15, 21, 35, 105
723 : 1, 3, 241, 723
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,820,732,105,723, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
820:2x 2x 5x 41
732:2x 2x 3x 61
105:3x 5x 7
723:3x 241
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 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 38003061146400/(1x1080)
LCM = 38003061146400/1080
LCM = 35188019580
Thus, we can understand that the LCM of 834,820,732,105,723 is 35188019580.
