Given numbers are 845,689,424,939,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,689,424,939,291 is 32633217240.
Find LCM of 845,689,424,939,291 with Prime Factorization
| 3 | 845, 689, 424, 939, 291 |
| 13 | 845, 689, 424, 313, 97 |
| 53 | 65, 53, 424, 313, 97 |
| 65, 1, 8, 313, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 53 x 65 x 1 x 8 x 313 x 97 = 32633217240
Therefore, the lowest common multiple of 845,689,424,939,291 is 32633217240.
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.
845 x 689 x 424 x 939 x 291 = 67452860035080
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.
845 : 1, 5, 13, 65, 169, 845
689 : 1, 13, 53, 689
424 : 1, 2, 4, 8, 53, 106, 212, 424
939 : 1, 3, 313, 939
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,689,424,939,291, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
689:13x 53
424:2x 2x 2x 53
939:3x 313
291:3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 53 = 2067
Therefore, the value for common factors is 2067.
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 = 67452860035080/(1x2067)
LCM = 67452860035080/2067
LCM = 32633217240
Thus, we can understand that the LCM of 845,689,424,939,291 is 32633217240.
