Given numbers are 249,785,845,975,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,785,845,975,819 is 3468526425.
Find LCM of 249,785,845,975,819 with Prime Factorization
| 3 | 249, 785, 845, 975, 819 |
| 5 | 83, 785, 845, 325, 273 |
| 13 | 83, 157, 169, 65, 273 |
| 83, 157, 13, 5, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 83 x 157 x 13 x 5 x 21 = 3468526425
Therefore, the lowest common multiple of 249,785,845,975,819 is 3468526425.
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.
249 x 785 x 845 x 975 x 819 = 131890717310625
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.
249 : 1, 3, 83, 249
785 : 1, 5, 157, 785
845 : 1, 5, 13, 65, 169, 845
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,785,845,975,819, is 1.
Now, the common factors can be found like this.
249:3x 83
785:5x 157
845:5x 13x 13
975:3x 5x 5x 13
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 13x 13 = 38025
Therefore, the value for common factors is 38025.
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 = 131890717310625/(1x38025)
LCM = 131890717310625/38025
LCM = 3468526425
Thus, we can understand that the LCM of 249,785,845,975,819 is 3468526425.
