Given numbers are 268,203,646,956,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 268,203,646,956,684 is 37798430292.
Find LCM of 268,203,646,956,684 with Prime Factorization
| 2 | 268, 203, 646, 956, 684 |
| 2 | 134, 203, 323, 478, 342 |
| 19 | 67, 203, 323, 239, 171 |
| 67, 203, 17, 239, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 67 x 203 x 17 x 239 x 9 = 37798430292
Therefore, the lowest common multiple of 268,203,646,956,684 is 37798430292.
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.
268 x 203 x 646 x 956 x 684 = 22981445617536
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.
268 : 1, 2, 4, 67, 134, 268
203 : 1, 7, 29, 203
646 : 1, 2, 17, 19, 34, 38, 323, 646
956 : 1, 2, 4, 239, 478, 956
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,203,646,956,684, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
203:7x 29
646:2x 17x 19
956:2x 2x 239
684:2x 2x 3x 3x 19
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 2x 19 = 608
Therefore, the value for common factors is 608.
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 = 22981445617536/(1x608)
LCM = 22981445617536/608
LCM = 37798430292
Thus, we can understand that the LCM of 268,203,646,956,684 is 37798430292.
