Given numbers are 128,817,172,589
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,817,172,589 is 3241856.
Find LCM of 128,817,172,589 with Prime Factorization
| 2 | 128, 817, 172, 589 |
| 2 | 64, 817, 86, 589 |
| 19 | 32, 817, 43, 589 |
| 43 | 32, 43, 43, 31 |
| 32, 1, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 43 x 32 x 1 x 1 x 31 = 3241856
Therefore, the lowest common multiple of 128,817,172,589 is 3241856.
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 817 x 172 x 589 = 10594385408
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
817 : 1, 19, 43, 817
172 : 1, 2, 4, 43, 86, 172
589 : 1, 19, 31, 589
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,817,172,589, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
817:19x 43
172:2x 2x 43
589:19x 31
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 19x 43 = 3268
Therefore, the value for common factors is 3268.
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 = 10594385408/(1x3268)
LCM = 10594385408/3268
LCM = 3241856
Thus, we can understand that the LCM of 128,817,172,589 is 3241856.
