Given numbers are 725,721,221,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,721,221,969 is 6584766825.
Find LCM of 725,721,221,969 with Prime Factorization
| 17 | 725, 721, 221, 969 |
| 725, 721, 13, 57 |
Multiply the prime numbers at the bottom and the left side.
17 x 725 x 721 x 13 x 57 = 6584766825
Therefore, the lowest common multiple of 725,721,221,969 is 6584766825.
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.
725 x 721 x 221 x 969 = 111941036025
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.
725 : 1, 5, 25, 29, 145, 725
721 : 1, 7, 103, 721
221 : 1, 13, 17, 221
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,721,221,969, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
721:7x 103
221:13x 17
969:3x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 111941036025/(1x17)
LCM = 111941036025/17
LCM = 6584766825
Thus, we can understand that the LCM of 725,721,221,969 is 6584766825.
