Given numbers are 308,821,385,328,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,821,385,328,146 is 7568339240.
Find LCM of 308,821,385,328,146 with Prime Factorization
| 2 | 308, 821, 385, 328, 146 |
| 2 | 154, 821, 385, 164, 73 |
| 7 | 77, 821, 385, 82, 73 |
| 11 | 11, 821, 55, 82, 73 |
| 1, 821, 5, 82, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 1 x 821 x 5 x 82 x 73 = 7568339240
Therefore, the lowest common multiple of 308,821,385,328,146 is 7568339240.
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.
308 x 821 x 385 x 328 x 146 = 4662096971840
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
821 : 1, 821
385 : 1, 5, 7, 11, 35, 55, 77, 385
328 : 1, 2, 4, 8, 41, 82, 164, 328
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,821,385,328,146, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
821:821
385:5x 7x 11
328:2x 2x 2x 41
146:2x 73
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 7x 11 = 616
Therefore, the value for common factors is 616.
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 = 4662096971840/(1x616)
LCM = 4662096971840/616
LCM = 7568339240
Thus, we can understand that the LCM of 308,821,385,328,146 is 7568339240.
