Find LCM of 858,297,165,370,215 with Prime Factorization
| 2 | 858, 297, 165, 370, 215 |
| 3 | 429, 297, 165, 185, 215 |
| 5 | 143, 99, 55, 185, 215 |
| 11 | 143, 99, 11, 37, 43 |
| 13, 9, 1, 37, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 9 x 1 x 37 x 43 = 61428510
Therefore, the lowest common multiple of 858,297,165,370,215 is 61428510.
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 297 x 165 x 370 x 215 = 3344782369500
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
297 : 1, 3, 9, 11, 27, 33, 99, 297
165 : 1, 3, 5, 11, 15, 33, 55, 165
370 : 1, 2, 5, 10, 37, 74, 185, 370
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,297,165,370,215, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
297:3x 3x 3x 11
165:3x 5x 11
370:2x 5x 37
215:5x 43
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 5x 5x 11x 11 = 54450
Therefore, the value for common factors is 54450.
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 = 3344782369500/(1x54450)
LCM = 3344782369500/54450
LCM = 61428510
Thus, we can understand that the LCM of 858,297,165,370,215 is 61428510.
