Given numbers are 208,120,520,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 208,120,520,515 is 321360.
Find LCM of 208,120,520,515 with Prime Factorization
| 2 | 208, 120, 520, 515 |
| 2 | 104, 60, 260, 515 |
| 2 | 52, 30, 130, 515 |
| 5 | 26, 15, 65, 515 |
| 13 | 26, 3, 13, 103 |
| 2, 3, 1, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 2 x 3 x 1 x 103 = 321360
Therefore, the lowest common multiple of 208,120,520,515 is 321360.
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.
208 x 120 x 520 x 515 = 6684288000
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,120,520,515, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
120:2x 2x 2x 3x 5
520:2x 2x 2x 5x 13
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 2x 2x 2x 2x 2x 5x 5x 13 = 20800
Therefore, the value for common factors is 20800.
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 = 6684288000/(1x20800)
LCM = 6684288000/20800
LCM = 321360
Thus, we can understand that the LCM of 208,120,520,515 is 321360.
