Given numbers are 352,409,560,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 352,409,560,405 is 408149280.
Find LCM of 352,409,560,405 with Prime Factorization
| 2 | 352, 409, 560, 405 |
| 2 | 176, 409, 280, 405 |
| 2 | 88, 409, 140, 405 |
| 2 | 44, 409, 70, 405 |
| 5 | 22, 409, 35, 405 |
| 22, 409, 7, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 22 x 409 x 7 x 81 = 408149280
Therefore, the lowest common multiple of 352,409,560,405 is 408149280.
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.
352 x 409 x 560 x 405 = 32651942400
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.
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
409 : 1, 409
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 352,409,560,405, is 1.
Now, the common factors can be found like this.
352:2x 2x 2x 2x 2x 11
409:409
560:2x 2x 2x 2x 5x 7
405:3x 3x 3x 3x 5
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 5 = 80
Therefore, the value for common factors is 80.
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 = 32651942400/(1x80)
LCM = 32651942400/80
LCM = 408149280
Thus, we can understand that the LCM of 352,409,560,405 is 408149280.
