Given numbers are 249,744,342,243,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,744,342,243,813 is 25754844888.
Find LCM of 249,744,342,243,813 with Prime Factorization
| 2 | 249, 744, 342, 243, 813 |
| 3 | 249, 372, 171, 243, 813 |
| 3 | 83, 124, 57, 81, 271 |
| 83, 124, 19, 27, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 83 x 124 x 19 x 27 x 271 = 25754844888
Therefore, the lowest common multiple of 249,744,342,243,813 is 25754844888.
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 744 x 342 x 243 x 813 = 12516854615568
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
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
243 : 1, 3, 9, 27, 81, 243
813 : 1, 3, 271, 813
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,744,342,243,813, is 3.
Now, the common factors can be found like this.
249:3x 83
744:2x 2x 2x 3x 31
342:2x 3x 3x 19
243:3x 3x 3x 3x 3
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 12516854615568/(3x162)
LCM = 12516854615568/486
LCM = 25754844888
Thus, we can understand that the LCM of 249,744,342,243,813 is 25754844888.
