Given numbers are 803,516,646,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,516,646,855 is 2007516060.
Find LCM of 803,516,646,855 with Prime Factorization
| 2 | 803, 516, 646, 855 |
| 3 | 803, 258, 323, 855 |
| 19 | 803, 86, 323, 285 |
| 803, 86, 17, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 803 x 86 x 17 x 15 = 2007516060
Therefore, the lowest common multiple of 803,516,646,855 is 2007516060.
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 516 x 646 x 855 = 228856830840
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
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
646 : 1, 2, 17, 19, 34, 38, 323, 646
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,516,646,855, is 1.
Now, the common factors can be found like this.
803:11x 73
516:2x 2x 3x 43
646:2x 17x 19
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 228856830840/(1x114)
LCM = 228856830840/114
LCM = 2007516060
Thus, we can understand that the LCM of 803,516,646,855 is 2007516060.
