Given numbers are 358,800,457,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 358,800,457,280 is 458096800.
Find LCM of 358,800,457,280 with Prime Factorization
| 2 | 358, 800, 457, 280 |
| 2 | 179, 400, 457, 140 |
| 2 | 179, 200, 457, 70 |
| 5 | 179, 100, 457, 35 |
| 179, 20, 457, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 179 x 20 x 457 x 7 = 458096800
Therefore, the lowest common multiple of 358,800,457,280 is 458096800.
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.
358 x 800 x 457 x 280 = 36647744000
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.
358 : 1, 2, 179, 358
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
457 : 1, 457
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 358,800,457,280, is 1.
Now, the common factors can be found like this.
358:2x 179
800:2x 2x 2x 2x 2x 5x 5
457:457
280:2x 2x 2x 5x 7
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 = 36647744000/(1x80)
LCM = 36647744000/80
LCM = 458096800
Thus, we can understand that the LCM of 358,800,457,280 is 458096800.
