Find LCM of 647,946,414,286,903 with Prime Factorization
| 2 | 647, 946, 414, 286, 903 |
| 3 | 647, 473, 207, 143, 903 |
| 11 | 647, 473, 69, 143, 301 |
| 43 | 647, 43, 69, 13, 301 |
| 647, 1, 69, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 43 x 647 x 1 x 69 x 13 x 7 = 11529411894
Therefore, the lowest common multiple of 647,946,414,286,903 is 11529411894.
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.
647 x 946 x 414 x 286 x 903 = 65440941910344
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.
647 : 1, 647
946 : 1, 2, 11, 22, 43, 86, 473, 946
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
286 : 1, 2, 11, 13, 22, 26, 143, 286
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,946,414,286,903, is 1.
Now, the common factors can be found like this.
647:647
946:2x 11x 43
414:2x 3x 3x 23
286:2x 11x 13
903:3x 7x 43
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 3x 11x 43 = 5676
Therefore, the value for common factors is 5676.
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 = 65440941910344/(1x5676)
LCM = 65440941910344/5676
LCM = 11529411894
Thus, we can understand that the LCM of 647,946,414,286,903 is 11529411894.
