Given numbers are 266,688,808,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 266,688,808,215 is 46209520.
Find LCM of 266,688,808,215 with Prime Factorization
| 2 | 266, 688, 808, 215 |
| 2 | 133, 344, 404, 215 |
| 2 | 133, 172, 202, 215 |
| 43 | 133, 86, 101, 215 |
| 133, 2, 101, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 43 x 133 x 2 x 101 x 5 = 46209520
Therefore, the lowest common multiple of 266,688,808,215 is 46209520.
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.
266 x 688 x 808 x 215 = 31792149760
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.
266 : 1, 2, 7, 14, 19, 38, 133, 266
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
808 : 1, 2, 4, 8, 101, 202, 404, 808
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 266,688,808,215, is 1.
Now, the common factors can be found like this.
266:2x 7x 19
688:2x 2x 2x 2x 43
808:2x 2x 2x 101
215:5x 43
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 2x 43 = 688
Therefore, the value for common factors is 688.
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 = 31792149760/(1x688)
LCM = 31792149760/688
LCM = 46209520
Thus, we can understand that the LCM of 266,688,808,215 is 46209520.
