Given numbers are 123,217,665,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,217,665,107 is 271314015.
Find LCM of 123,217,665,107 with Prime Factorization
| 7 | 123, 217, 665, 107 |
| 123, 31, 95, 107 |
Multiply the prime numbers at the bottom and the left side.
7 x 123 x 31 x 95 x 107 = 271314015
Therefore, the lowest common multiple of 123,217,665,107 is 271314015.
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.
123 x 217 x 665 x 107 = 1899198105
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.
123 : 1, 3, 41, 123
217 : 1, 7, 31, 217
665 : 1, 5, 7, 19, 35, 95, 133, 665
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,217,665,107, is 1.
Now, the common factors can be found like this.
123:3x 41
217:7x 31
665:5x 7x 19
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 1899198105/(1x7)
LCM = 1899198105/7
LCM = 271314015
Thus, we can understand that the LCM of 123,217,665,107 is 271314015.
