Given numbers are 516,540,360,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 516,540,360,255 is 789480.
Find LCM of 516,540,360,255 with Prime Factorization
| 2 | 516, 540, 360, 255 |
| 2 | 258, 270, 180, 255 |
| 3 | 129, 135, 90, 255 |
| 3 | 43, 45, 30, 85 |
| 5 | 43, 15, 10, 85 |
| 43, 3, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 43 x 3 x 2 x 17 = 789480
Therefore, the lowest common multiple of 516,540,360,255 is 789480.
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.
516 x 540 x 360 x 255 = 25579152000
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
255 : 1, 3, 5, 15, 17, 51, 85, 255
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,540,360,255, is 3.
Now, the common factors can be found like this.
516:2x 2x 3x 43
540:2x 2x 3x 3x 3x 5
360:2x 2x 2x 3x 3x 5
255:3x 5x 17
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 3x 3x 5x 5 = 10800
Therefore, the value for common factors is 10800.
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 = 25579152000/(3x10800)
LCM = 25579152000/32400
LCM = 789480
Thus, we can understand that the LCM of 516,540,360,255 is 789480.
