Find LCM of 441,285,916,486,665 with Prime Factorization
| 2 | 441, 285, 916, 486, 665 |
| 3 | 441, 285, 458, 243, 665 |
| 3 | 147, 95, 458, 81, 665 |
| 5 | 49, 95, 458, 27, 665 |
| 7 | 49, 19, 458, 27, 133 |
| 19 | 7, 19, 458, 27, 19 |
| 7, 1, 458, 27, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 19 x 7 x 1 x 458 x 27 x 1 = 1036147140
Therefore, the lowest common multiple of 441,285,916,486,665 is 1036147140.
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 285 x 916 x 486 x 665 = 37208043797400
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
285 : 1, 3, 5, 15, 19, 57, 95, 285
916 : 1, 2, 4, 229, 458, 916
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,285,916,486,665, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
285:3x 5x 19
916:2x 2x 229
486:2x 3x 3x 3x 3x 3
665:5x 7x 19
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 5x 7x 19 = 35910
Therefore, the value for common factors is 35910.
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 = 37208043797400/(1x35910)
LCM = 37208043797400/35910
LCM = 1036147140
Thus, we can understand that the LCM of 441,285,916,486,665 is 1036147140.
