Given numbers are 879,403,869,721,729
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 879,403,869,721,729 is 53933081661459.
Find LCM of 879,403,869,721,729 with Prime Factorization
| 3 | 879, 403, 869, 721, 729 |
| 293, 403, 869, 721, 243 |
Multiply the prime numbers at the bottom and the left side.
3 x 293 x 403 x 869 x 721 x 243 = 53933081661459
Therefore, the lowest common multiple of 879,403,869,721,729 is 53933081661459.
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.
879 x 403 x 869 x 721 x 729 = 161799244984377
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.
879 : 1, 3, 293, 879
403 : 1, 13, 31, 403
869 : 1, 11, 79, 869
721 : 1, 7, 103, 721
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 879,403,869,721,729, is 1.
Now, the common factors can be found like this.
879:3x 293
403:13x 31
869:11x 79
721:7x 103
729:3x 3x 3x 3x 3x 3
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 = 161799244984377/(1x3)
LCM = 161799244984377/3
LCM = 53933081661459
Thus, we can understand that the LCM of 879,403,869,721,729 is 53933081661459.
