Given numbers are 515,387,141,306
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,387,141,306 is 318489390.
Find LCM of 515,387,141,306 with Prime Factorization
| 3 | 515, 387, 141, 306 |
| 3 | 515, 129, 47, 102 |
| 515, 43, 47, 34 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 515 x 43 x 47 x 34 = 318489390
Therefore, the lowest common multiple of 515,387,141,306 is 318489390.
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.
515 x 387 x 141 x 306 = 8599213530
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.
515 : 1, 5, 103, 515
387 : 1, 3, 9, 43, 129, 387
141 : 1, 3, 47, 141
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,387,141,306, is 1.
Now, the common factors can be found like this.
515:5x 103
387:3x 3x 43
141:3x 47
306:2x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 8599213530/(1x27)
LCM = 8599213530/27
LCM = 318489390
Thus, we can understand that the LCM of 515,387,141,306 is 318489390.
