Given numbers are 517,987,342,432
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,987,342,432 is 29704752.
Find LCM of 517,987,342,432 with Prime Factorization
| 2 | 517, 987, 342, 432 |
| 3 | 517, 987, 171, 216 |
| 3 | 517, 329, 57, 72 |
| 47 | 517, 329, 19, 24 |
| 11, 7, 19, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 11 x 7 x 19 x 24 = 29704752
Therefore, the lowest common multiple of 517,987,342,432 is 29704752.
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.
517 x 987 x 342 x 432 = 75390660576
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.
517 : 1, 11, 47, 517
987 : 1, 3, 7, 21, 47, 141, 329, 987
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,987,342,432, is 1.
Now, the common factors can be found like this.
517:11x 47
987:3x 7x 47
342:2x 3x 3x 19
432:2x 2x 2x 2x 3x 3x 3
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 3x 3x 47 = 2538
Therefore, the value for common factors is 2538.
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 = 75390660576/(1x2538)
LCM = 75390660576/2538
LCM = 29704752
Thus, we can understand that the LCM of 517,987,342,432 is 29704752.
