Given numbers are 111,440,668,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,440,668,231 is 57093960.
Find LCM of 111,440,668,231 with Prime Factorization
| 2 | 111, 440, 668, 231 |
| 2 | 111, 220, 334, 231 |
| 3 | 111, 110, 167, 231 |
| 11 | 37, 110, 167, 77 |
| 37, 10, 167, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 37 x 10 x 167 x 7 = 57093960
Therefore, the lowest common multiple of 111,440,668,231 is 57093960.
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 440 x 668 x 231 = 7536402720
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
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
668 : 1, 2, 4, 167, 334, 668
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,440,668,231, is 1.
Now, the common factors can be found like this.
111:3x 37
440:2x 2x 2x 5x 11
668:2x 2x 167
231:3x 7x 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 2x 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 7536402720/(1x132)
LCM = 7536402720/132
LCM = 57093960
Thus, we can understand that the LCM of 111,440,668,231 is 57093960.
