Given numbers are 114,694,309,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 114,694,309,721 is 28521318.
Find LCM of 114,694,309,721 with Prime Factorization
| 2 | 114, 694, 309, 721 |
| 3 | 57, 347, 309, 721 |
| 103 | 19, 347, 103, 721 |
| 19, 347, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 19 x 347 x 1 x 7 = 28521318
Therefore, the lowest common multiple of 114,694,309,721 is 28521318.
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.
114 x 694 x 309 x 721 = 17626174524
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.
114 : 1, 2, 3, 6, 19, 38, 57, 114
694 : 1, 2, 347, 694
309 : 1, 3, 103, 309
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 114,694,309,721, is 1.
Now, the common factors can be found like this.
114:2x 3x 19
694:2x 347
309:3x 103
721:7x 103
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 103 = 618
Therefore, the value for common factors is 618.
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 = 17626174524/(1x618)
LCM = 17626174524/618
LCM = 28521318
Thus, we can understand that the LCM of 114,694,309,721 is 28521318.
