Given numbers are 668,910,366,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,910,366,122 is 55621020.
Find LCM of 668,910,366,122 with Prime Factorization
| 2 | 668, 910, 366, 122 |
| 61 | 334, 455, 183, 61 |
| 334, 455, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 61 x 334 x 455 x 3 x 1 = 55621020
Therefore, the lowest common multiple of 668,910,366,122 is 55621020.
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.
668 x 910 x 366 x 122 = 27143057760
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.
668 : 1, 2, 4, 167, 334, 668
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
366 : 1, 2, 3, 6, 61, 122, 183, 366
122 : 1, 2, 61, 122
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,910,366,122, is 2.
Now, the common factors can be found like this.
668:2x 2x 167
910:2x 5x 7x 13
366:2x 3x 61
122:2x 61
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 61 = 244
Therefore, the value for common factors is 244.
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 = 27143057760/(2x244)
LCM = 27143057760/488
LCM = 55621020
Thus, we can understand that the LCM of 668,910,366,122 is 55621020.
