Given numbers are 400,225,860,676,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,225,860,676,285 is 497062800.
Find LCM of 400,225,860,676,285 with Prime Factorization
| 2 | 400, 225, 860, 676, 285 |
| 2 | 200, 225, 430, 338, 285 |
| 3 | 100, 225, 215, 169, 285 |
| 5 | 100, 75, 215, 169, 95 |
| 5 | 20, 15, 43, 169, 19 |
| 4, 3, 43, 169, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 4 x 3 x 43 x 169 x 19 = 497062800
Therefore, the lowest common multiple of 400,225,860,676,285 is 497062800.
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.
400 x 225 x 860 x 676 x 285 = 14911884000000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
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 400,225,860,676,285, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
225:3x 3x 5x 5
860:2x 2x 5x 43
676:2x 2x 13x 13
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 2x 2x 3x 5x 5x 5x 5 = 30000
Therefore, the value for common factors is 30000.
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 = 14911884000000/(1x30000)
LCM = 14911884000000/30000
LCM = 497062800
Thus, we can understand that the LCM of 400,225,860,676,285 is 497062800.
