Find LCM of 916,206,216,913,561 with Prime Factorization
| 2 | 916, 206, 216, 913, 561 |
| 2 | 458, 103, 108, 913, 561 |
| 3 | 229, 103, 54, 913, 561 |
| 11 | 229, 103, 18, 913, 187 |
| 229, 103, 18, 83, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 229 x 103 x 18 x 83 x 17 = 79076266632
Therefore, the lowest common multiple of 916,206,216,913,561 is 79076266632.
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.
916 x 206 x 216 x 913 x 561 = 20876134390848
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.
916 : 1, 2, 4, 229, 458, 916
206 : 1, 2, 103, 206
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
913 : 1, 11, 83, 913
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,206,216,913,561, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
206:2x 103
216:2x 2x 2x 3x 3x 3
913:11x 83
561:3x 11x 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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 20876134390848/(1x264)
LCM = 20876134390848/264
LCM = 79076266632
Thus, we can understand that the LCM of 916,206,216,913,561 is 79076266632.
