Given numbers are 515,721,273,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,721,273,408 is 19120920.
Find LCM of 515,721,273,408 with Prime Factorization
3 | 515, 721, 273, 408 |
7 | 515, 721, 91, 136 |
103 | 515, 103, 13, 136 |
5, 1, 13, 136 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 103 x 5 x 1 x 13 x 136 = 19120920
Therefore, the lowest common multiple of 515,721,273,408 is 19120920.
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.
515 x 721 x 273 x 408 = 41358549960
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.
515 : 1, 5, 103, 515
721 : 1, 7, 103, 721
273 : 1, 3, 7, 13, 21, 39, 91, 273
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,721,273,408, is 1.
Now, the common factors can be found like this.
515:5x 103
721:7x 103
273:3x 7x 13
408:2x 2x 2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 103 = 2163
Therefore, the value for common factors is 2163.
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 = 41358549960/(1x2163)
LCM = 41358549960/2163
LCM = 19120920
Thus, we can understand that the LCM of 515,721,273,408 is 19120920.
