Given numbers are 721,201,897,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,201,897,309 is 43331379.
Find LCM of 721,201,897,309 with Prime Factorization
| 3 | 721, 201, 897, 309 |
| 103 | 721, 67, 299, 103 |
| 7, 67, 299, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 7 x 67 x 299 x 1 = 43331379
Therefore, the lowest common multiple of 721,201,897,309 is 43331379.
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.
721 x 201 x 897 x 309 = 40168188333
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.
721 : 1, 7, 103, 721
201 : 1, 3, 67, 201
897 : 1, 3, 13, 23, 39, 69, 299, 897
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,201,897,309, is 1.
Now, the common factors can be found like this.
721:7x 103
201:3x 67
897:3x 13x 23
309:3x 103
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 103 = 927
Therefore, the value for common factors is 927.
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 = 40168188333/(1x927)
LCM = 40168188333/927
LCM = 43331379
Thus, we can understand that the LCM of 721,201,897,309 is 43331379.
