Given numbers are 285,109,442,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,109,442,993 is 4544871630.
Find LCM of 285,109,442,993 with Prime Factorization
| 3 | 285, 109, 442, 993 |
| 95, 109, 442, 331 |
Multiply the prime numbers at the bottom and the left side.
3 x 95 x 109 x 442 x 331 = 4544871630
Therefore, the lowest common multiple of 285,109,442,993 is 4544871630.
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.
285 x 109 x 442 x 993 = 13634614890
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.
285 : 1, 3, 5, 15, 19, 57, 95, 285
109 : 1, 109
442 : 1, 2, 13, 17, 26, 34, 221, 442
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,109,442,993, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
109:109
442:2x 13x 17
993:3x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 13634614890/(1x3)
LCM = 13634614890/3
LCM = 4544871630
Thus, we can understand that the LCM of 285,109,442,993 is 4544871630.
