Given numbers are 121,267,741,903,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,267,741,903,215 is 12009642645.
Find LCM of 121,267,741,903,215 with Prime Factorization
| 3 | 121, 267, 741, 903, 215 |
| 43 | 121, 89, 247, 301, 215 |
| 121, 89, 247, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 121 x 89 x 247 x 7 x 5 = 12009642645
Therefore, the lowest common multiple of 121,267,741,903,215 is 12009642645.
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.
121 x 267 x 741 x 903 x 215 = 4647731703615
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.
121 : 1, 11, 121
267 : 1, 3, 89, 267
741 : 1, 3, 13, 19, 39, 57, 247, 741
903 : 1, 3, 7, 21, 43, 129, 301, 903
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,267,741,903,215, is 1.
Now, the common factors can be found like this.
121:11x 11
267:3x 89
741:3x 13x 19
903:3x 7x 43
215:5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 43 = 387
Therefore, the value for common factors is 387.
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 = 4647731703615/(1x387)
LCM = 4647731703615/387
LCM = 12009642645
Thus, we can understand that the LCM of 121,267,741,903,215 is 12009642645.
