Given numbers are 678,404,227,162,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,404,227,162,450 is 20985083100.
Find LCM of 678,404,227,162,450 with Prime Factorization
| 2 | 678, 404, 227, 162, 450 |
| 3 | 339, 202, 227, 81, 225 |
| 3 | 113, 202, 227, 27, 75 |
| 113, 202, 227, 9, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 113 x 202 x 227 x 9 x 25 = 20985083100
Therefore, the lowest common multiple of 678,404,227,162,450 is 20985083100.
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.
678 x 404 x 227 x 162 x 450 = 4532777949600
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
404 : 1, 2, 4, 101, 202, 404
227 : 1, 227
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
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 678,404,227,162,450, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
404:2x 2x 101
227:227
162:2x 3x 3x 3x 3
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 4532777949600/(1x216)
LCM = 4532777949600/216
LCM = 20985083100
Thus, we can understand that the LCM of 678,404,227,162,450 is 20985083100.
