Given numbers are 361,789,312,646,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,789,312,646,845 is 32732548680.
Find LCM of 361,789,312,646,845 with Prime Factorization
| 2 | 361, 789, 312, 646, 845 |
| 3 | 361, 789, 156, 323, 845 |
| 13 | 361, 263, 52, 323, 845 |
| 19 | 361, 263, 4, 323, 65 |
| 19, 263, 4, 17, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 19 x 263 x 4 x 17 x 65 = 32732548680
Therefore, the lowest common multiple of 361,789,312,646,845 is 32732548680.
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.
361 x 789 x 312 x 646 x 845 = 48509637143760
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.
361 : 1, 19, 361
789 : 1, 3, 263, 789
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
646 : 1, 2, 17, 19, 34, 38, 323, 646
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,789,312,646,845, is 1.
Now, the common factors can be found like this.
361:19x 19
789:3x 263
312:2x 2x 2x 3x 13
646:2x 17x 19
845:5x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 19 = 1482
Therefore, the value for common factors is 1482.
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 = 48509637143760/(1x1482)
LCM = 48509637143760/1482
LCM = 32732548680
Thus, we can understand that the LCM of 361,789,312,646,845 is 32732548680.
