Find LCM of 405,648,706,895 with Prime Factorization
| 2 | 405, 648, 706, 895 |
| 3 | 405, 324, 353, 895 |
| 3 | 135, 108, 353, 895 |
| 3 | 45, 36, 353, 895 |
| 3 | 15, 12, 353, 895 |
| 5 | 5, 4, 353, 895 |
| 1, 4, 353, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 5 x 1 x 4 x 353 x 179 = 204725880
Therefore, the lowest common multiple of 405,648,706,895 is 204725880.
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 648 x 706 x 895 = 165827962800
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
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
706 : 1, 2, 353, 706
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,648,706,895, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
648:2x 2x 2x 3x 3x 3x 3
706:2x 353
895:5x 179
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 5 = 810
Therefore, the value for common factors is 810.
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 = 165827962800/(1x810)
LCM = 165827962800/810
LCM = 204725880
Thus, we can understand that the LCM of 405,648,706,895 is 204725880.
