Given numbers are 128,943,647,451,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,943,647,451,575 is 21476259200.
Find LCM of 128,943,647,451,575 with Prime Factorization
| 23 | 128, 943, 647, 451, 575 |
| 41 | 128, 41, 647, 451, 25 |
| 128, 1, 647, 11, 25 |
Multiply the prime numbers at the bottom and the left side.
23 x 41 x 128 x 1 x 647 x 11 x 25 = 21476259200
Therefore, the lowest common multiple of 128,943,647,451,575 is 21476259200.
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.
128 x 943 x 647 x 451 x 575 = 20252112425600
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
943 : 1, 23, 41, 943
647 : 1, 647
451 : 1, 11, 41, 451
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,943,647,451,575, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
943:23x 41
647:647
451:11x 41
575:5x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 41 = 943
Therefore, the value for common factors is 943.
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 = 20252112425600/(1x943)
LCM = 20252112425600/943
LCM = 21476259200
Thus, we can understand that the LCM of 128,943,647,451,575 is 21476259200.
