Find LCM of 441,786,408,108,221 with Prime Factorization
| 2 | 441, 786, 408, 108, 221 |
| 2 | 441, 393, 204, 54, 221 |
| 3 | 441, 393, 102, 27, 221 |
| 3 | 147, 131, 34, 9, 221 |
| 17 | 49, 131, 34, 3, 221 |
| 49, 131, 2, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 49 x 131 x 2 x 3 x 13 = 306417384
Therefore, the lowest common multiple of 441,786,408,108,221 is 306417384.
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.
441 x 786 x 408 x 108 x 221 = 3375493902144
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
786 : 1, 2, 3, 6, 131, 262, 393, 786
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,786,408,108,221, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
786:2x 3x 131
408:2x 2x 2x 3x 17
108:2x 2x 3x 3x 3
221:13x 17
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 17 = 11016
Therefore, the value for common factors is 11016.
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 = 3375493902144/(1x11016)
LCM = 3375493902144/11016
LCM = 306417384
Thus, we can understand that the LCM of 441,786,408,108,221 is 306417384.
