The LCM of 713,891,858,689 is 875419974.
Find LCM of 713,891,858,689 with Prime Factorization
| 3 | 713, 891, 858, 689 |
| 11 | 713, 297, 286, 689 |
| 13 | 713, 27, 26, 689 |
| 713, 27, 2, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 713 x 27 x 2 x 53 = 875419974
Therefore, the lowest common multiple of 713,891,858,689 is 875419974.
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.
713 x 891 x 858 x 689 = 375555168846
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.
713 : 1, 23, 31, 713
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,891,858,689, is 1.
Now, the common factors can be found like this.
713:23x 31
891:3x 3x 3x 3x 11
858:2x 3x 11x 13
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 13 = 429
Therefore, the value for common factors is 429.
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 = 375555168846/(1x429)
LCM = 375555168846/429
LCM = 875419974
Thus, we can understand that the LCM of 713,891,858,689 is 875419974.
