Given numbers are 716,898,916,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 716,898,916,285 is 20981653260.
Find LCM of 716,898,916,285 with Prime Factorization
| 2 | 716, 898, 916, 285 |
| 2 | 358, 449, 458, 285 |
| 179, 449, 229, 285 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 179 x 449 x 229 x 285 = 20981653260
Therefore, the lowest common multiple of 716,898,916,285 is 20981653260.
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.
716 x 898 x 916 x 285 = 167853226080
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.
716 : 1, 2, 4, 179, 358, 716
898 : 1, 2, 449, 898
916 : 1, 2, 4, 229, 458, 916
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,898,916,285, is 1.
Now, the common factors can be found like this.
716:2x 2x 179
898:2x 449
916:2x 2x 229
285:3x 5x 19
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 2 = 8
Therefore, the value for common factors is 8.
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 = 167853226080/(1x8)
LCM = 167853226080/8
LCM = 20981653260
Thus, we can understand that the LCM of 716,898,916,285 is 20981653260.
