Given numbers are 589,115,647,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 589,115,647,645 is 5653366305.
Find LCM of 589,115,647,645 with Prime Factorization
| 5 | 589, 115, 647, 645 |
| 589, 23, 647, 129 |
Multiply the prime numbers at the bottom and the left side.
5 x 589 x 23 x 647 x 129 = 5653366305
Therefore, the lowest common multiple of 589,115,647,645 is 5653366305.
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.
589 x 115 x 647 x 645 = 28266831525
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.
589 : 1, 19, 31, 589
115 : 1, 5, 23, 115
647 : 1, 647
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 589,115,647,645, is 1.
Now, the common factors can be found like this.
589:19x 31
115:5x 23
647:647
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 28266831525/(1x5)
LCM = 28266831525/5
LCM = 5653366305
Thus, we can understand that the LCM of 589,115,647,645 is 5653366305.
