Given numbers are 783,803,858,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,803,858,715 is 81737370.
Find LCM of 783,803,858,715 with Prime Factorization
| 3 | 783, 803, 858, 715 |
| 11 | 261, 803, 286, 715 |
| 13 | 261, 73, 26, 65 |
| 261, 73, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 261 x 73 x 2 x 5 = 81737370
Therefore, the lowest common multiple of 783,803,858,715 is 81737370.
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.
783 x 803 x 858 x 715 = 385718649030
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
803 : 1, 11, 73, 803
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,803,858,715, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
803:11x 73
858:2x 3x 11x 13
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11x 13 = 4719
Therefore, the value for common factors is 4719.
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 = 385718649030/(1x4719)
LCM = 385718649030/4719
LCM = 81737370
Thus, we can understand that the LCM of 783,803,858,715 is 81737370.
