Given numbers are 856,702,885,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,702,885,450 is 443172600.
Find LCM of 856,702,885,450 with Prime Factorization
| 2 | 856, 702, 885, 450 |
| 3 | 428, 351, 885, 225 |
| 3 | 428, 117, 295, 75 |
| 5 | 428, 39, 295, 25 |
| 428, 39, 59, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 428 x 39 x 59 x 5 = 443172600
Therefore, the lowest common multiple of 856,702,885,450 is 443172600.
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.
856 x 702 x 885 x 450 = 239313204000
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
885 : 1, 3, 5, 15, 59, 177, 295, 885
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,702,885,450, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
702:2x 3x 3x 3x 13
885:3x 5x 59
450:2x 3x 3x 5x 5
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 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 239313204000/(1x540)
LCM = 239313204000/540
LCM = 443172600
Thus, we can understand that the LCM of 856,702,885,450 is 443172600.
