Given numbers are 123,390,645,604,112
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,390,645,604,112 is 5814091920.
Find LCM of 123,390,645,604,112 with Prime Factorization
| 2 | 123, 390, 645, 604, 112 |
| 2 | 123, 195, 645, 302, 56 |
| 3 | 123, 195, 645, 151, 28 |
| 5 | 41, 65, 215, 151, 28 |
| 41, 13, 43, 151, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 41 x 13 x 43 x 151 x 28 = 5814091920
Therefore, the lowest common multiple of 123,390,645,604,112 is 5814091920.
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 390 x 645 x 604 x 112 = 2093073091200
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
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
645 : 1, 3, 5, 15, 43, 129, 215, 645
604 : 1, 2, 4, 151, 302, 604
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,390,645,604,112, is 1.
Now, the common factors can be found like this.
123:3x 41
390:2x 3x 5x 13
645:3x 5x 43
604:2x 2x 151
112:2x 2x 2x 2x 7
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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 2093073091200/(1x360)
LCM = 2093073091200/360
LCM = 5814091920
Thus, we can understand that the LCM of 123,390,645,604,112 is 5814091920.
