Given numbers are 422,816,680,906
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,816,680,906 is 129992880.
Find LCM of 422,816,680,906 with Prime Factorization
| 2 | 422, 816, 680, 906 |
| 2 | 211, 408, 340, 453 |
| 2 | 211, 204, 170, 453 |
| 3 | 211, 102, 85, 453 |
| 17 | 211, 34, 85, 151 |
| 211, 2, 5, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 211 x 2 x 5 x 151 = 129992880
Therefore, the lowest common multiple of 422,816,680,906 is 129992880.
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.
422 x 816 x 680 x 906 = 212148380160
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.
422 : 1, 2, 211, 422
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
906 : 1, 2, 3, 6, 151, 302, 453, 906
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,816,680,906, is 2.
Now, the common factors can be found like this.
422:2x 211
816:2x 2x 2x 2x 3x 17
680:2x 2x 2x 5x 17
906:2x 3x 151
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 2x 3x 17 = 816
Therefore, the value for common factors is 816.
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 = 212148380160/(2x816)
LCM = 212148380160/1632
LCM = 129992880
Thus, we can understand that the LCM of 422,816,680,906 is 129992880.
