Given numbers are 363,921,253,545,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 363,921,253,545,621 is 12572216415.
Find LCM of 363,921,253,545,621 with Prime Factorization
| 3 | 363, 921, 253, 545, 621 |
| 11 | 121, 307, 253, 545, 207 |
| 23 | 11, 307, 23, 545, 207 |
| 11, 307, 1, 545, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 11 x 307 x 1 x 545 x 9 = 12572216415
Therefore, the lowest common multiple of 363,921,253,545,621 is 12572216415.
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.
363 x 921 x 253 x 545 x 621 = 28626936776955
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.
363 : 1, 3, 11, 33, 121, 363
921 : 1, 3, 307, 921
253 : 1, 11, 23, 253
545 : 1, 5, 109, 545
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,921,253,545,621, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
921:3x 307
253:11x 23
545:5x 109
621:3x 3x 3x 23
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 11x 23 = 2277
Therefore, the value for common factors is 2277.
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 = 28626936776955/(1x2277)
LCM = 28626936776955/2277
LCM = 12572216415
Thus, we can understand that the LCM of 363,921,253,545,621 is 12572216415.
