Given numbers are 684,818,782,838,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,818,782,838,345 is 229160728620.
Find LCM of 684,818,782,838,345 with Prime Factorization
| 2 | 684, 818, 782, 838, 345 |
| 3 | 342, 409, 391, 419, 345 |
| 23 | 114, 409, 391, 419, 115 |
| 114, 409, 17, 419, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 114 x 409 x 17 x 419 x 5 = 229160728620
Therefore, the lowest common multiple of 684,818,782,838,345 is 229160728620.
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.
684 x 818 x 782 x 838 x 345 = 126496722198240
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
818 : 1, 2, 409, 818
782 : 1, 2, 17, 23, 34, 46, 391, 782
838 : 1, 2, 419, 838
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,818,782,838,345, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
818:2x 409
782:2x 17x 23
838:2x 419
345:3x 5x 23
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 23 = 552
Therefore, the value for common factors is 552.
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 = 126496722198240/(1x552)
LCM = 126496722198240/552
LCM = 229160728620
Thus, we can understand that the LCM of 684,818,782,838,345 is 229160728620.
