Given numbers are 312,668,991,286,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,668,991,286,195 is 2839928520.
Find LCM of 312,668,991,286,195 with Prime Factorization
| 2 | 312, 668, 991, 286, 195 |
| 2 | 156, 334, 991, 143, 195 |
| 3 | 78, 167, 991, 143, 195 |
| 13 | 26, 167, 991, 143, 65 |
| 2, 167, 991, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 2 x 167 x 991 x 11 x 5 = 2839928520
Therefore, the lowest common multiple of 312,668,991,286,195 is 2839928520.
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 668 x 991 x 286 x 195 = 11518750077120
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
668 : 1, 2, 4, 167, 334, 668
991 : 1, 991
286 : 1, 2, 11, 13, 22, 26, 143, 286
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,668,991,286,195, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
668:2x 2x 167
991:991
286:2x 11x 13
195:3x 5x 13
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 3x 13x 13 = 4056
Therefore, the value for common factors is 4056.
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 = 11518750077120/(1x4056)
LCM = 11518750077120/4056
LCM = 2839928520
Thus, we can understand that the LCM of 312,668,991,286,195 is 2839928520.
