Find LCM of 860,726,408,646,105 with Prime Factorization
2 | 860, 726, 408, 646, 105 |
2 | 430, 363, 204, 323, 105 |
3 | 215, 363, 102, 323, 105 |
5 | 215, 121, 34, 323, 35 |
17 | 43, 121, 34, 323, 7 |
43, 121, 2, 19, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 43 x 121 x 2 x 19 x 7 = 1411677960
Therefore, the lowest common multiple of 860,726,408,646,105 is 1411677960.
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.
860 x 726 x 408 x 646 x 105 = 17278938230400
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
646 : 1, 2, 17, 19, 34, 38, 323, 646
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,726,408,646,105, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
726:2x 3x 11x 11
408:2x 2x 2x 3x 17
646:2x 17x 19
105:3x 5x 7
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 3x 3x 5x 17 = 12240
Therefore, the value for common factors is 12240.
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 = 17278938230400/(1x12240)
LCM = 17278938230400/12240
LCM = 1411677960
Thus, we can understand that the LCM of 860,726,408,646,105 is 1411677960.
