Find LCM of 858,396,361,330,660 with Prime Factorization
| 2 | 858, 396, 361, 330, 660 |
| 2 | 429, 198, 361, 165, 330 |
| 3 | 429, 99, 361, 165, 165 |
| 5 | 143, 33, 361, 55, 55 |
| 11 | 143, 33, 361, 11, 11 |
| 13, 3, 361, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 13 x 3 x 361 x 1 x 1 = 9292140
Therefore, the lowest common multiple of 858,396,361,330,660 is 9292140.
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.
858 x 396 x 361 x 330 x 660 = 26714530814400
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
361 : 1, 19, 361
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,396,361,330,660, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
396:2x 2x 3x 3x 11
361:19x 19
330:2x 3x 5x 11
660:2x 2x 3x 5x 11
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 3x 3x 3x 5x 11x 11x 11 = 2874960
Therefore, the value for common factors is 2874960.
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 = 26714530814400/(1x2874960)
LCM = 26714530814400/2874960
LCM = 9292140
Thus, we can understand that the LCM of 858,396,361,330,660 is 9292140.
