Find LCM of 858,748,833,931 with Prime Factorization
| 2 | 858, 748, 833, 931 |
| 7 | 429, 374, 833, 931 |
| 7 | 429, 374, 119, 133 |
| 11 | 429, 374, 17, 19 |
| 17 | 39, 34, 17, 19 |
| 39, 2, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 11 x 17 x 39 x 2 x 1 x 19 = 27159132
Therefore, the lowest common multiple of 858,748,833,931 is 27159132.
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 748 x 833 x 931 = 497718253032
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
833 : 1, 7, 17, 49, 119, 833
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,748,833,931, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
748:2x 2x 11x 17
833:7x 7x 17
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 11x 17 = 18326
Therefore, the value for common factors is 18326.
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 = 497718253032/(1x18326)
LCM = 497718253032/18326
LCM = 27159132
Thus, we can understand that the LCM of 858,748,833,931 is 27159132.
