Given numbers are 172,817,212,388,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,817,212,388,181 is 3040942628.
Find LCM of 172,817,212,388,181 with Prime Factorization
| 2 | 172, 817, 212, 388, 181 |
| 2 | 86, 817, 106, 194, 181 |
| 43 | 43, 817, 53, 97, 181 |
| 1, 19, 53, 97, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 1 x 19 x 53 x 97 x 181 = 3040942628
Therefore, the lowest common multiple of 172,817,212,388,181 is 3040942628.
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.
172 x 817 x 212 x 388 x 181 = 2092168528064
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.
172 : 1, 2, 4, 43, 86, 172
817 : 1, 19, 43, 817
212 : 1, 2, 4, 53, 106, 212
388 : 1, 2, 4, 97, 194, 388
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,817,212,388,181, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
817:19x 43
212:2x 2x 53
388:2x 2x 97
181:181
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 2x 2x 43 = 688
Therefore, the value for common factors is 688.
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 = 2092168528064/(1x688)
LCM = 2092168528064/688
LCM = 3040942628
Thus, we can understand that the LCM of 172,817,212,388,181 is 3040942628.
