Given numbers are 412,647,432,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 412,647,432,647 is 28788912.
Find LCM of 412,647,432,647 with Prime Factorization
| 2 | 412, 647, 432, 647 |
| 2 | 206, 647, 216, 647 |
| 647 | 103, 647, 108, 647 |
| 103, 1, 108, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 647 x 103 x 1 x 108 x 1 = 28788912
Therefore, the lowest common multiple of 412,647,432,647 is 28788912.
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.
412 x 647 x 432 x 647 = 74505704256
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.
412 : 1, 2, 4, 103, 206, 412
647 : 1, 647
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 412,647,432,647, is 1.
Now, the common factors can be found like this.
412:2x 2x 103
647:647
432:2x 2x 2x 2x 3x 3x 3
647:647
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 647 = 2588
Therefore, the value for common factors is 2588.
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 = 74505704256/(1x2588)
LCM = 74505704256/2588
LCM = 28788912
Thus, we can understand that the LCM of 412,647,432,647 is 28788912.
