Given numbers are 455,328,325,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,328,325,394 is 147001400.
Find LCM of 455,328,325,394 with Prime Factorization
| 2 | 455, 328, 325, 394 |
| 5 | 455, 164, 325, 197 |
| 13 | 91, 164, 65, 197 |
| 7, 164, 5, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 7 x 164 x 5 x 197 = 147001400
Therefore, the lowest common multiple of 455,328,325,394 is 147001400.
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.
455 x 328 x 325 x 394 = 19110182000
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
328 : 1, 2, 4, 8, 41, 82, 164, 328
325 : 1, 5, 13, 25, 65, 325
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,328,325,394, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
328:2x 2x 2x 41
325:5x 5x 13
394:2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 19110182000/(1x130)
LCM = 19110182000/130
LCM = 147001400
Thus, we can understand that the LCM of 455,328,325,394 is 147001400.
