Given numbers are 309,597,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,597,639 is 13097583.
Find LCM of 309,597,639 with Prime Factorization
| 3 | 309, 597, 639 |
| 103, 199, 213 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 199 x 213 = 13097583
Therefore, the lowest common multiple of 309,597,639 is 13097583.
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.
309 x 597 x 639 = 117878247
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.
309 : 1, 3, 103, 309
597 : 1, 3, 199, 597
639 : 1, 3, 9, 71, 213, 639
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,597,639, is 3.
Now, the common factors can be found like this.
309:3x 103
597:3x 199
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 117878247/(3x3)
LCM = 117878247/9
LCM = 13097583
Thus, we can understand that the LCM of 309,597,639 is 13097583.
