Given numbers are 299,852,642,243,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 299,852,642,243,165 is 121434550380.
Find LCM of 299,852,642,243,165 with Prime Factorization
| 2 | 299, 852, 642, 243, 165 |
| 3 | 299, 426, 321, 243, 165 |
| 299, 142, 107, 81, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 299 x 142 x 107 x 81 x 55 = 121434550380
Therefore, the lowest common multiple of 299,852,642,243,165 is 121434550380.
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.
299 x 852 x 642 x 243 x 165 = 6557465720520
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.
299 : 1, 13, 23, 299
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
642 : 1, 2, 3, 6, 107, 214, 321, 642
243 : 1, 3, 9, 27, 81, 243
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,852,642,243,165, is 1.
Now, the common factors can be found like this.
299:13x 23
852:2x 2x 3x 71
642:2x 3x 107
243:3x 3x 3x 3x 3
165:3x 5x 11
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 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 6557465720520/(1x54)
LCM = 6557465720520/54
LCM = 121434550380
Thus, we can understand that the LCM of 299,852,642,243,165 is 121434550380.
