Given numbers are 721,675,455,885
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,675,455,885 is 373279725.
Find LCM of 721,675,455,885 with Prime Factorization
| 3 | 721, 675, 455, 885 |
| 5 | 721, 225, 455, 295 |
| 7 | 721, 45, 91, 59 |
| 103, 45, 13, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 103 x 45 x 13 x 59 = 373279725
Therefore, the lowest common multiple of 721,675,455,885 is 373279725.
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 675 x 455 x 885 = 195971855625
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
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
455 : 1, 5, 7, 13, 35, 65, 91, 455
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,675,455,885, is 1.
Now, the common factors can be found like this.
721:7x 103
675:3x 3x 3x 5x 5
455:5x 7x 13
885:3x 5x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 7 = 525
Therefore, the value for common factors is 525.
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 = 195971855625/(1x525)
LCM = 195971855625/525
LCM = 373279725
Thus, we can understand that the LCM of 721,675,455,885 is 373279725.
