Given numbers are 646,726,514,704,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,726,514,704,221 is 25070650176.
Find LCM of 646,726,514,704,221 with Prime Factorization
| 2 | 646, 726, 514, 704, 221 |
| 11 | 323, 363, 257, 352, 221 |
| 17 | 323, 33, 257, 32, 221 |
| 19, 33, 257, 32, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 19 x 33 x 257 x 32 x 13 = 25070650176
Therefore, the lowest common multiple of 646,726,514,704,221 is 25070650176.
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.
646 x 726 x 514 x 704 x 221 = 37505692663296
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
514 : 1, 2, 257, 514
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,726,514,704,221, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
726:2x 3x 11x 11
514:2x 257
704:2x 2x 2x 2x 2x 2x 11
221:13x 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 2x 11x 17 = 1496
Therefore, the value for common factors is 1496.
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 = 37505692663296/(1x1496)
LCM = 37505692663296/1496
LCM = 25070650176
Thus, we can understand that the LCM of 646,726,514,704,221 is 25070650176.
