Given numbers are 679,127,159,388,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 679,127,159,388,381 is 54844188.
Find LCM of 679,127,159,388,381 with Prime Factorization
| 3 | 679, 127, 159, 388, 381 |
| 97 | 679, 127, 53, 388, 127 |
| 127 | 7, 127, 53, 4, 127 |
| 7, 1, 53, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 97 x 127 x 7 x 1 x 53 x 4 x 1 = 54844188
Therefore, the lowest common multiple of 679,127,159,388,381 is 54844188.
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.
679 x 127 x 159 x 388 x 381 = 2026876655916
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.
679 : 1, 7, 97, 679
127 : 1, 127
159 : 1, 3, 53, 159
388 : 1, 2, 4, 97, 194, 388
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,127,159,388,381, is 1.
Now, the common factors can be found like this.
679:7x 97
127:127
159:3x 53
388:2x 2x 97
381:3x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 97x 127 = 36957
Therefore, the value for common factors is 36957.
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 = 2026876655916/(1x36957)
LCM = 2026876655916/36957
LCM = 54844188
Thus, we can understand that the LCM of 679,127,159,388,381 is 54844188.
