Given numbers are 909,721,207,207
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,721,207,207 is 15073947.
Find LCM of 909,721,207,207 with Prime Factorization
| 3 | 909, 721, 207, 207 |
| 3 | 303, 721, 69, 69 |
| 23 | 101, 721, 23, 23 |
| 101, 721, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 101 x 721 x 1 x 1 = 15073947
Therefore, the lowest common multiple of 909,721,207,207 is 15073947.
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.
909 x 721 x 207 x 207 = 28082763261
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.
909 : 1, 3, 9, 101, 303, 909
721 : 1, 7, 103, 721
207 : 1, 3, 9, 23, 69, 207
207 : 1, 3, 9, 23, 69, 207
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,721,207,207, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
721:7x 103
207:3x 3x 23
207:3x 3x 23
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 3x 3x 23 = 1863
Therefore, the value for common factors is 1863.
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 = 28082763261/(1x1863)
LCM = 28082763261/1863
LCM = 15073947
Thus, we can understand that the LCM of 909,721,207,207 is 15073947.
