Given numbers are 168,943,574,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,943,574,668 is 26456808.
Find LCM of 168,943,574,668 with Prime Factorization
| 2 | 168, 943, 574, 668 |
| 2 | 84, 943, 287, 334 |
| 7 | 42, 943, 287, 167 |
| 41 | 6, 943, 41, 167 |
| 6, 23, 1, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 41 x 6 x 23 x 1 x 167 = 26456808
Therefore, the lowest common multiple of 168,943,574,668 is 26456808.
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.
168 x 943 x 574 x 668 = 60744831168
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
943 : 1, 23, 41, 943
574 : 1, 2, 7, 14, 41, 82, 287, 574
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,943,574,668, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
943:23x 41
574:2x 7x 41
668:2x 2x 167
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 2x 7x 41 = 2296
Therefore, the value for common factors is 2296.
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 = 60744831168/(1x2296)
LCM = 60744831168/2296
LCM = 26456808
Thus, we can understand that the LCM of 168,943,574,668 is 26456808.
