Given numbers are 111,654,891,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,654,891,436 is 14373612.
Find LCM of 111,654,891,436 with Prime Factorization
| 2 | 111, 654, 891, 436 |
| 3 | 111, 327, 891, 218 |
| 109 | 37, 109, 297, 218 |
| 37, 1, 297, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 37 x 1 x 297 x 2 = 14373612
Therefore, the lowest common multiple of 111,654,891,436 is 14373612.
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 654 x 891 x 436 = 28201026744
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
654 : 1, 2, 3, 6, 109, 218, 327, 654
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,654,891,436, is 1.
Now, the common factors can be found like this.
111:3x 37
654:2x 3x 109
891:3x 3x 3x 3x 11
436:2x 2x 109
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 109 = 1962
Therefore, the value for common factors is 1962.
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 = 28201026744/(1x1962)
LCM = 28201026744/1962
LCM = 14373612
Thus, we can understand that the LCM of 111,654,891,436 is 14373612.
