Find LCM of 408,641,672,192,585 with Prime Factorization
| 2 | 408, 641, 672, 192, 585 |
| 2 | 204, 641, 336, 96, 585 |
| 2 | 102, 641, 168, 48, 585 |
| 2 | 51, 641, 84, 24, 585 |
| 2 | 51, 641, 42, 12, 585 |
| 3 | 51, 641, 21, 6, 585 |
| 17, 641, 7, 2, 195 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 17 x 641 x 7 x 2 x 195 = 2855885760
Therefore, the lowest common multiple of 408,641,672,192,585 is 2855885760.
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.
408 x 641 x 672 x 192 x 585 = 19739882373120
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
641 : 1, 641
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,641,672,192,585, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
641:641
672:2x 2x 2x 2x 2x 3x 7
192:2x 2x 2x 2x 2x 2x 3
585:3x 3x 5x 13
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 2x 2x 2x 2x 2x 3x 3x 3 = 6912
Therefore, the value for common factors is 6912.
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 = 19739882373120/(1x6912)
LCM = 19739882373120/6912
LCM = 2855885760
Thus, we can understand that the LCM of 408,641,672,192,585 is 2855885760.
