Given numbers are 312,600,642,996
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,600,642,996 is 69271800.
Find LCM of 312,600,642,996 with Prime Factorization
| 2 | 312, 600, 642, 996 |
| 2 | 156, 300, 321, 498 |
| 2 | 78, 150, 321, 249 |
| 3 | 39, 75, 321, 249 |
| 13, 25, 107, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 25 x 107 x 83 = 69271800
Therefore, the lowest common multiple of 312,600,642,996 is 69271800.
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.
312 x 600 x 642 x 996 = 119701670400
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
642 : 1, 2, 3, 6, 107, 214, 321, 642
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,600,642,996, is 6.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
600:2x 2x 2x 3x 5x 5
642:2x 3x 107
996:2x 2x 3x 83
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 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 119701670400/(6x288)
LCM = 119701670400/1728
LCM = 69271800
Thus, we can understand that the LCM of 312,600,642,996 is 69271800.
