Given numbers are 509,689,442,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 509,689,442,221 is 11923834.
Find LCM of 509,689,442,221 with Prime Factorization
| 13 | 509, 689, 442, 221 |
| 17 | 509, 53, 34, 17 |
| 509, 53, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 509 x 53 x 2 x 1 = 11923834
Therefore, the lowest common multiple of 509,689,442,221 is 11923834.
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.
509 x 689 x 442 x 221 = 34257175082
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.
509 : 1, 509
689 : 1, 13, 53, 689
442 : 1, 2, 13, 17, 26, 34, 221, 442
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,689,442,221, is 1.
Now, the common factors can be found like this.
509:509
689:13x 53
442:2x 13x 17
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13x 17 = 2873
Therefore, the value for common factors is 2873.
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 = 34257175082/(1x2873)
LCM = 34257175082/2873
LCM = 11923834
Thus, we can understand that the LCM of 509,689,442,221 is 11923834.
