Given numbers are 278,684,261,357,206
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,684,261,357,206 is 33795049428.
Find LCM of 278,684,261,357,206 with Prime Factorization
| 2 | 278, 684, 261, 357, 206 |
| 3 | 139, 342, 261, 357, 103 |
| 3 | 139, 114, 87, 119, 103 |
| 139, 38, 29, 119, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 139 x 38 x 29 x 119 x 103 = 33795049428
Therefore, the lowest common multiple of 278,684,261,357,206 is 33795049428.
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.
278 x 684 x 261 x 357 x 206 = 3649865338224
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.
278 : 1, 2, 139, 278
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
261 : 1, 3, 9, 29, 87, 261
357 : 1, 3, 7, 17, 21, 51, 119, 357
206 : 1, 2, 103, 206
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,684,261,357,206, is 1.
Now, the common factors can be found like this.
278:2x 139
684:2x 2x 3x 3x 19
261:3x 3x 29
357:3x 7x 17
206:2x 103
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 3649865338224/(1x108)
LCM = 3649865338224/108
LCM = 33795049428
Thus, we can understand that the LCM of 278,684,261,357,206 is 33795049428.
