The LCM of 405,898,917,630,901 is 300486860730.
Find LCM of 405,898,917,630,901 with Prime Factorization
| 2 | 405, 898, 917, 630, 901 |
| 3 | 405, 449, 917, 315, 901 |
| 3 | 135, 449, 917, 105, 901 |
| 5 | 45, 449, 917, 35, 901 |
| 7 | 9, 449, 917, 7, 901 |
| 9, 449, 131, 1, 901 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 9 x 449 x 131 x 1 x 901 = 300486860730
Therefore, the lowest common multiple of 405,898,917,630,901 is 300486860730.
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.
405 x 898 x 917 x 630 x 901 = 189306722259900
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
898 : 1, 2, 449, 898
917 : 1, 7, 131, 917
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,898,917,630,901, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
898:2x 449
917:7x 131
630:2x 3x 3x 5x 7
901:17x 53
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 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 189306722259900/(1x630)
LCM = 189306722259900/630
LCM = 300486860730
Thus, we can understand that the LCM of 405,898,917,630,901 is 300486860730.
