Given numbers are 3,390,400,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3,390,400,515 is 1606800.
Find LCM of 3,390,400,515 with Prime Factorization
| 2 | 3, 390, 400, 515 |
| 3 | 3, 195, 200, 515 |
| 5 | 1, 65, 200, 515 |
| 1, 13, 40, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 1 x 13 x 40 x 103 = 1606800
Therefore, the lowest common multiple of 3,390,400,515 is 1606800.
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.
3 x 390 x 400 x 515 = 241020000
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.
3 : 1, 3
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,390,400,515, is 1.
Now, the common factors can be found like this.
3:3
390:2x 3x 5x 13
400:2x 2x 2x 2x 5x 5
515:5x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 241020000/(1x150)
LCM = 241020000/150
LCM = 1606800
Thus, we can understand that the LCM of 3,390,400,515 is 1606800.
