Given numbers are 389,172,645,501,204
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,172,645,501,204 is 2849277180.
Find LCM of 389,172,645,501,204 with Prime Factorization
| 2 | 389, 172, 645, 501, 204 |
| 2 | 389, 86, 645, 501, 102 |
| 3 | 389, 43, 645, 501, 51 |
| 43 | 389, 43, 215, 167, 17 |
| 389, 1, 5, 167, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 389 x 1 x 5 x 167 x 17 = 2849277180
Therefore, the lowest common multiple of 389,172,645,501,204 is 2849277180.
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.
389 x 172 x 645 x 501 x 204 = 4410681074640
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.
389 : 1, 389
172 : 1, 2, 4, 43, 86, 172
645 : 1, 3, 5, 15, 43, 129, 215, 645
501 : 1, 3, 167, 501
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,172,645,501,204, is 1.
Now, the common factors can be found like this.
389:389
172:2x 2x 43
645:3x 5x 43
501:3x 167
204:2x 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.
2x 2x 3x 3x 43 = 1548
Therefore, the value for common factors is 1548.
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 = 4410681074640/(1x1548)
LCM = 4410681074640/1548
LCM = 2849277180
Thus, we can understand that the LCM of 389,172,645,501,204 is 2849277180.
