Given numbers are 721,217,646,527
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,217,646,527 is 14438746.
Find LCM of 721,217,646,527 with Prime Factorization
| 7 | 721, 217, 646, 527 |
| 17 | 103, 31, 646, 527 |
| 31 | 103, 31, 38, 31 |
| 103, 1, 38, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 17 x 31 x 103 x 1 x 38 x 1 = 14438746
Therefore, the lowest common multiple of 721,217,646,527 is 14438746.
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 217 x 646 x 527 = 53264533994
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
217 : 1, 7, 31, 217
646 : 1, 2, 17, 19, 34, 38, 323, 646
527 : 1, 17, 31, 527
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,217,646,527, is 1.
Now, the common factors can be found like this.
721:7x 103
217:7x 31
646:2x 17x 19
527:17x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 17x 31 = 3689
Therefore, the value for common factors is 3689.
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 = 53264533994/(1x3689)
LCM = 53264533994/3689
LCM = 14438746
Thus, we can understand that the LCM of 721,217,646,527 is 14438746.
