Find LCM of 897,356,715,858,730 with Prime Factorization
| 2 | 897, 356, 715, 858, 730 |
| 3 | 897, 178, 715, 429, 365 |
| 5 | 299, 178, 715, 143, 365 |
| 11 | 299, 178, 143, 143, 73 |
| 13 | 299, 178, 13, 13, 73 |
| 23, 178, 1, 1, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 23 x 178 x 1 x 1 x 73 = 1282117980
Therefore, the lowest common multiple of 897,356,715,858,730 is 1282117980.
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 356 x 715 x 858 x 730 = 143007439489200
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
356 : 1, 2, 4, 89, 178, 356
715 : 1, 5, 11, 13, 55, 65, 143, 715
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
730 : 1, 2, 5, 10, 73, 146, 365, 730
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,356,715,858,730, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
356:2x 2x 89
715:5x 11x 13
858:2x 3x 11x 13
730:2x 5x 73
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 3x 5x 11x 13x 13 = 111540
Therefore, the value for common factors is 111540.
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 = 143007439489200/(1x111540)
LCM = 143007439489200/111540
LCM = 1282117980
Thus, we can understand that the LCM of 897,356,715,858,730 is 1282117980.
