Given numbers are 721,649,915,535
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,649,915,535 is 45812588745.
Find LCM of 721,649,915,535 with Prime Factorization
| 5 | 721, 649, 915, 535 |
| 721, 649, 183, 107 |
Multiply the prime numbers at the bottom and the left side.
5 x 721 x 649 x 183 x 107 = 45812588745
Therefore, the lowest common multiple of 721,649,915,535 is 45812588745.
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 649 x 915 x 535 = 229062943725
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
649 : 1, 11, 59, 649
915 : 1, 3, 5, 15, 61, 183, 305, 915
535 : 1, 5, 107, 535
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,649,915,535, is 1.
Now, the common factors can be found like this.
721:7x 103
649:11x 59
915:3x 5x 61
535:5x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 229062943725/(1x5)
LCM = 229062943725/5
LCM = 45812588745
Thus, we can understand that the LCM of 721,649,915,535 is 45812588745.
