Given numbers are 328,160,768,698
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 328,160,768,698 is 54946560.
Find LCM of 328,160,768,698 with Prime Factorization
| 2 | 328, 160, 768, 698 |
| 2 | 164, 80, 384, 349 |
| 2 | 82, 40, 192, 349 |
| 2 | 41, 20, 96, 349 |
| 2 | 41, 10, 48, 349 |
| 41, 5, 24, 349 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 41 x 5 x 24 x 349 = 54946560
Therefore, the lowest common multiple of 328,160,768,698 is 54946560.
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.
328 x 160 x 768 x 698 = 28132638720
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
698 : 1, 2, 349, 698
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,160,768,698, is 2.
Now, the common factors can be found like this.
328:2x 2x 2x 41
160:2x 2x 2x 2x 2x 5
768:2x 2x 2x 2x 2x 2x 2x 2x 3
698:2x 349
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 2 = 256
Therefore, the value for common factors is 256.
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 = 28132638720/(2x256)
LCM = 28132638720/512
LCM = 54946560
Thus, we can understand that the LCM of 328,160,768,698 is 54946560.
