Given numbers are 559,115,221,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 559,115,221,805 is 7649915.
Find LCM of 559,115,221,805 with Prime Factorization
| 5 | 559, 115, 221, 805 |
| 13 | 559, 23, 221, 161 |
| 23 | 43, 23, 17, 161 |
| 43, 1, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 23 x 43 x 1 x 17 x 7 = 7649915
Therefore, the lowest common multiple of 559,115,221,805 is 7649915.
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.
559 x 115 x 221 x 805 = 11436622925
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.
559 : 1, 13, 43, 559
115 : 1, 5, 23, 115
221 : 1, 13, 17, 221
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 559,115,221,805, is 1.
Now, the common factors can be found like this.
559:13x 43
115:5x 23
221:13x 17
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 23 = 1495
Therefore, the value for common factors is 1495.
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 = 11436622925/(1x1495)
LCM = 11436622925/1495
LCM = 7649915
Thus, we can understand that the LCM of 559,115,221,805 is 7649915.
