Given numbers are 239,364,551,845,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 239,364,551,845,645 is 401933264460.
Find LCM of 239,364,551,845,645 with Prime Factorization
| 5 | 239, 364, 551, 845, 645 |
| 13 | 239, 364, 551, 169, 129 |
| 239, 28, 551, 13, 129 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 239 x 28 x 551 x 13 x 129 = 401933264460
Therefore, the lowest common multiple of 239,364,551,845,645 is 401933264460.
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.
239 x 364 x 551 x 845 x 645 = 26125662189900
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.
239 : 1, 239
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
551 : 1, 19, 29, 551
845 : 1, 5, 13, 65, 169, 845
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,364,551,845,645, is 1.
Now, the common factors can be found like this.
239:239
364:2x 2x 7x 13
551:19x 29
845:5x 13x 13
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13 = 65
Therefore, the value for common factors is 65.
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 = 26125662189900/(1x65)
LCM = 26125662189900/65
LCM = 401933264460
Thus, we can understand that the LCM of 239,364,551,845,645 is 401933264460.
