The LCM of 858,721,377,858 is 17939922.
Find LCM of 858,721,377,858 with Prime Factorization
| 2 | 858, 721, 377, 858 |
| 3 | 429, 721, 377, 429 |
| 11 | 143, 721, 377, 143 |
| 13 | 13, 721, 377, 13 |
| 1, 721, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 1 x 721 x 29 x 1 = 17939922
Therefore, the lowest common multiple of 858,721,377,858 is 17939922.
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 721 x 377 x 858 = 200101889988
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
721 : 1, 7, 103, 721
377 : 1, 13, 29, 377
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,721,377,858, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
721:7x 103
377:13x 29
858:2x 3x 11x 13
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 11x 13x 13 = 11154
Therefore, the value for common factors is 11154.
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 = 200101889988/(1x11154)
LCM = 200101889988/11154
LCM = 17939922
Thus, we can understand that the LCM of 858,721,377,858 is 17939922.
