Given numbers are 906,898,218,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,898,218,642 is 4744438422.
Find LCM of 906,898,218,642 with Prime Factorization
| 2 | 906, 898, 218, 642 |
| 3 | 453, 449, 109, 321 |
| 151, 449, 109, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 151 x 449 x 109 x 107 = 4744438422
Therefore, the lowest common multiple of 906,898,218,642 is 4744438422.
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.
906 x 898 x 218 x 642 = 113866522128
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
898 : 1, 2, 449, 898
218 : 1, 2, 109, 218
642 : 1, 2, 3, 6, 107, 214, 321, 642
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,898,218,642, is 2.
Now, the common factors can be found like this.
906:2x 3x 151
898:2x 449
218:2x 109
642:2x 3x 107
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 3 = 12
Therefore, the value for common factors is 12.
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 = 113866522128/(2x12)
LCM = 113866522128/24
LCM = 4744438422
Thus, we can understand that the LCM of 906,898,218,642 is 4744438422.
