Given numbers are 331,589,646,544
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,589,646,544 is 106057696.
Find LCM of 331,589,646,544 with Prime Factorization
| 2 | 331, 589, 646, 544 |
| 17 | 331, 589, 323, 272 |
| 19 | 331, 589, 19, 16 |
| 331, 31, 1, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 331 x 31 x 1 x 16 = 106057696
Therefore, the lowest common multiple of 331,589,646,544 is 106057696.
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.
331 x 589 x 646 x 544 = 68513271616
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.
331 : 1, 331
589 : 1, 19, 31, 589
646 : 1, 2, 17, 19, 34, 38, 323, 646
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,589,646,544, is 1.
Now, the common factors can be found like this.
331:331
589:19x 31
646:2x 17x 19
544:2x 2x 2x 2x 2x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 19 = 646
Therefore, the value for common factors is 646.
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 = 68513271616/(1x646)
LCM = 68513271616/646
LCM = 106057696
Thus, we can understand that the LCM of 331,589,646,544 is 106057696.
