Find LCM of 684,407,699,342,831 with Prime Factorization
| 2 | 684, 407, 699, 342, 831 |
| 3 | 342, 407, 699, 171, 831 |
| 3 | 114, 407, 233, 57, 277 |
| 19 | 38, 407, 233, 19, 277 |
| 2, 407, 233, 1, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 2 x 407 x 233 x 1 x 277 = 17967439908
Therefore, the lowest common multiple of 684,407,699,342,831 is 17967439908.
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 407 x 699 x 342 x 831 = 55303780036824
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
407 : 1, 11, 37, 407
699 : 1, 3, 233, 699
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,407,699,342,831, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
407:11x 37
699:3x 233
342:2x 3x 3x 19
831:3x 277
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 3x 3x 3x 19 = 3078
Therefore, the value for common factors is 3078.
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 = 55303780036824/(1x3078)
LCM = 55303780036824/3078
LCM = 17967439908
Thus, we can understand that the LCM of 684,407,699,342,831 is 17967439908.
