Given numbers are 115,966,921,206,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,966,921,206,149 is 22756685070.
Find LCM of 115,966,921,206,149 with Prime Factorization
| 2 | 115, 966, 921, 206, 149 |
| 3 | 115, 483, 921, 103, 149 |
| 23 | 115, 161, 307, 103, 149 |
| 5, 7, 307, 103, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 5 x 7 x 307 x 103 x 149 = 22756685070
Therefore, the lowest common multiple of 115,966,921,206,149 is 22756685070.
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.
115 x 966 x 921 x 206 x 149 = 3140422539660
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.
115 : 1, 5, 23, 115
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
921 : 1, 3, 307, 921
206 : 1, 2, 103, 206
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,966,921,206,149, is 1.
Now, the common factors can be found like this.
115:5x 23
966:2x 3x 7x 23
921:3x 307
206:2x 103
149:149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 3140422539660/(1x138)
LCM = 3140422539660/138
LCM = 22756685070
Thus, we can understand that the LCM of 115,966,921,206,149 is 22756685070.
