Find LCM of 897,858,616,888 with Prime Factorization
| 2 | 897, 858, 616, 888 |
| 2 | 897, 429, 308, 444 |
| 2 | 897, 429, 154, 222 |
| 3 | 897, 429, 77, 111 |
| 11 | 299, 143, 77, 37 |
| 13 | 299, 13, 7, 37 |
| 23, 1, 7, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 13 x 23 x 1 x 7 x 37 = 20444424
Therefore, the lowest common multiple of 897,858,616,888 is 20444424.
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.
897 x 858 x 616 x 888 = 420991579008
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,858,616,888, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
858:2x 3x 11x 13
616:2x 2x 2x 7x 11
888:2x 2x 2x 3x 37
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 11x 13 = 20592
Therefore, the value for common factors is 20592.
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 = 420991579008/(1x20592)
LCM = 420991579008/20592
LCM = 20444424
Thus, we can understand that the LCM of 897,858,616,888 is 20444424.
