Given numbers are 803,913,830,646,435
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,913,830,646,435 is 18729035490.
Find LCM of 803,913,830,646,435 with Prime Factorization
| 2 | 803, 913, 830, 646, 435 |
| 5 | 803, 913, 415, 323, 435 |
| 11 | 803, 913, 83, 323, 87 |
| 83 | 73, 83, 83, 323, 87 |
| 73, 1, 1, 323, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 83 x 73 x 1 x 1 x 323 x 87 = 18729035490
Therefore, the lowest common multiple of 803,913,830,646,435 is 18729035490.
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.
803 x 913 x 830 x 646 x 435 = 170996094023700
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.
803 : 1, 11, 73, 803
913 : 1, 11, 83, 913
830 : 1, 2, 5, 10, 83, 166, 415, 830
646 : 1, 2, 17, 19, 34, 38, 323, 646
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,913,830,646,435, is 1.
Now, the common factors can be found like this.
803:11x 73
913:11x 83
830:2x 5x 83
646:2x 17x 19
435:3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 83 = 9130
Therefore, the value for common factors is 9130.
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 = 170996094023700/(1x9130)
LCM = 170996094023700/9130
LCM = 18729035490
Thus, we can understand that the LCM of 803,913,830,646,435 is 18729035490.
