Given numbers are 426,447,858,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,447,858,451 is 372148062.
Find LCM of 426,447,858,451 with Prime Factorization
| 2 | 426, 447, 858, 451 |
| 3 | 213, 447, 429, 451 |
| 11 | 71, 149, 143, 451 |
| 71, 149, 13, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 71 x 149 x 13 x 41 = 372148062
Therefore, the lowest common multiple of 426,447,858,451 is 372148062.
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.
426 x 447 x 858 x 451 = 73685316276
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
447 : 1, 3, 149, 447
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,447,858,451, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
447:3x 149
858:2x 3x 11x 13
451:11x 41
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 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 73685316276/(1x198)
LCM = 73685316276/198
LCM = 372148062
Thus, we can understand that the LCM of 426,447,858,451 is 372148062.
