Find LCM of 220,405,810,640,325 with Prime Factorization
| 2 | 220, 405, 810, 640, 325 |
| 2 | 110, 405, 405, 320, 325 |
| 3 | 55, 405, 405, 160, 325 |
| 3 | 55, 135, 135, 160, 325 |
| 3 | 55, 45, 45, 160, 325 |
| 3 | 55, 15, 15, 160, 325 |
| 5 | 55, 5, 5, 160, 325 |
| 11, 1, 1, 32, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 5 x 11 x 1 x 1 x 32 x 65 = 37065600
Therefore, the lowest common multiple of 220,405,810,640,325 is 37065600.
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.
220 x 405 x 810 x 640 x 325 = 15011568000000
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
325 : 1, 5, 13, 25, 65, 325
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,405,810,640,325, is 5.
Now, the common factors can be found like this.
220:2x 2x 5x 11
405:3x 3x 3x 3x 5
810:2x 3x 3x 3x 3x 5
640:2x 2x 2x 2x 2x 2x 2x 5
325:5x 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 3x 3x 3x 3x 5x 5x 5 = 81000
Therefore, the value for common factors is 81000.
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 = 15011568000000/(5x81000)
LCM = 15011568000000/405000
LCM = 37065600
Thus, we can understand that the LCM of 220,405,810,640,325 is 37065600.
