Given numbers are 115,121,460,169
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,121,460,169 is 9406540.
Find LCM of 115,121,460,169 with Prime Factorization
| 5 | 115, 121, 460, 169 |
| 23 | 23, 121, 92, 169 |
| 1, 121, 4, 169 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 1 x 121 x 4 x 169 = 9406540
Therefore, the lowest common multiple of 115,121,460,169 is 9406540.
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 121 x 460 x 169 = 1081752100
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
121 : 1, 11, 121
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,121,460,169, is 1.
Now, the common factors can be found like this.
115:5x 23
121:11x 11
460:2x 2x 5x 23
169:13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 1081752100/(1x115)
LCM = 1081752100/115
LCM = 9406540
Thus, we can understand that the LCM of 115,121,460,169 is 9406540.
