Find LCM of 213,355,311,660,442 with Prime Factorization
2 | 213, 355, 311, 660, 442 |
3 | 213, 355, 311, 330, 221 |
5 | 71, 355, 311, 110, 221 |
71 | 71, 71, 311, 22, 221 |
1, 1, 311, 22, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 71 x 1 x 1 x 311 x 22 x 221 = 3220734660
Therefore, the lowest common multiple of 213,355,311,660,442 is 3220734660.
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.
213 x 355 x 311 x 660 x 442 = 6860164825800
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.
213 : 1, 3, 71, 213
355 : 1, 5, 71, 355
311 : 1, 311
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,355,311,660,442, is 1.
Now, the common factors can be found like this.
213:3x 71
355:5x 71
311:311
660:2x 2x 3x 5x 11
442:2x 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 3x 5x 71 = 2130
Therefore, the value for common factors is 2130.
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 = 6860164825800/(1x2130)
LCM = 6860164825800/2130
LCM = 3220734660
Thus, we can understand that the LCM of 213,355,311,660,442 is 3220734660.
