Find LCM of 312,636,451,858 with Prime Factorization
| 2 | 312, 636, 451, 858 |
| 2 | 156, 318, 451, 429 |
| 3 | 78, 159, 451, 429 |
| 11 | 26, 53, 451, 143 |
| 13 | 26, 53, 41, 13 |
| 2, 53, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 2 x 53 x 41 x 1 = 7457736
Therefore, the lowest common multiple of 312,636,451,858 is 7457736.
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.
312 x 636 x 451 x 858 = 76784849856
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
451 : 1, 11, 41, 451
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 312,636,451,858, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
636:2x 2x 3x 53
451:11x 41
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 2x 2x 3x 3x 11x 13 = 10296
Therefore, the value for common factors is 10296.
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 = 76784849856/(1x10296)
LCM = 76784849856/10296
LCM = 7457736
Thus, we can understand that the LCM of 312,636,451,858 is 7457736.
