Given numbers are 400,335,656,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,335,656,816 is 56038800.
Find LCM of 400,335,656,816 with Prime Factorization
| 2 | 400, 335, 656, 816 |
| 2 | 200, 335, 328, 408 |
| 2 | 100, 335, 164, 204 |
| 2 | 50, 335, 82, 102 |
| 5 | 25, 335, 41, 51 |
| 5, 67, 41, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 5 x 67 x 41 x 51 = 56038800
Therefore, the lowest common multiple of 400,335,656,816 is 56038800.
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.
400 x 335 x 656 x 816 = 71729664000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
335 : 1, 5, 67, 335
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,335,656,816, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
335:5x 67
656:2x 2x 2x 2x 41
816:2x 2x 2x 2x 3x 17
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 2x 2x 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 71729664000/(1x1280)
LCM = 71729664000/1280
LCM = 56038800
Thus, we can understand that the LCM of 400,335,656,816 is 56038800.
