Given numbers are 111,905,551,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,905,551,642 is 11845050870.
Find LCM of 111,905,551,642 with Prime Factorization
| 3 | 111, 905, 551, 642 |
| 37, 905, 551, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 905 x 551 x 214 = 11845050870
Therefore, the lowest common multiple of 111,905,551,642 is 11845050870.
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.
111 x 905 x 551 x 642 = 35535152610
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.
111 : 1, 3, 37, 111
905 : 1, 5, 181, 905
551 : 1, 19, 29, 551
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,905,551,642, is 1.
Now, the common factors can be found like this.
111:3x 37
905:5x 181
551:19x 29
642:2x 3x 107
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 = 35535152610/(1x3)
LCM = 35535152610/3
LCM = 11845050870
Thus, we can understand that the LCM of 111,905,551,642 is 11845050870.
