Given numbers are 828,996,785,664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 828,996,785,664 is 107896680.
Find LCM of 828,996,785,664 with Prime Factorization
| 2 | 828, 996, 785, 664 |
| 2 | 414, 498, 785, 332 |
| 3 | 207, 249, 785, 166 |
| 83 | 69, 83, 785, 166 |
| 69, 1, 785, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 83 x 69 x 1 x 785 x 2 = 107896680
Therefore, the lowest common multiple of 828,996,785,664 is 107896680.
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.
828 x 996 x 785 x 664 = 429860373120
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
785 : 1, 5, 157, 785
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,996,785,664, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
996:2x 2x 3x 83
785:5x 157
664:2x 2x 2x 83
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 83 = 3984
Therefore, the value for common factors is 3984.
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 = 429860373120/(1x3984)
LCM = 429860373120/3984
LCM = 107896680
Thus, we can understand that the LCM of 828,996,785,664 is 107896680.
