Given numbers are 867,208,786,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,208,786,338 is 307112208.
Find LCM of 867,208,786,338 with Prime Factorization
| 2 | 867, 208, 786, 338 |
| 3 | 867, 104, 393, 169 |
| 13 | 289, 104, 131, 169 |
| 289, 8, 131, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 289 x 8 x 131 x 13 = 307112208
Therefore, the lowest common multiple of 867,208,786,338 is 307112208.
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.
867 x 208 x 786 x 338 = 47909504448
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.
867 : 1, 3, 17, 51, 289, 867
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
786 : 1, 2, 3, 6, 131, 262, 393, 786
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,208,786,338, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
208:2x 2x 2x 2x 13
786:2x 3x 131
338:2x 13x 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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 47909504448/(1x156)
LCM = 47909504448/156
LCM = 307112208
Thus, we can understand that the LCM of 867,208,786,338 is 307112208.
