Find LCM of 116,986,179,178,221 with Prime Factorization
| 2 | 116, 986, 179, 178, 221 |
| 17 | 58, 493, 179, 89, 221 |
| 29 | 58, 29, 179, 89, 13 |
| 2, 1, 179, 89, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 29 x 2 x 1 x 179 x 89 x 13 = 408407116
Therefore, the lowest common multiple of 116,986,179,178,221 is 408407116.
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.
116 x 986 x 179 x 178 x 221 = 805378832752
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.
116 : 1, 2, 4, 29, 58, 116
986 : 1, 2, 17, 29, 34, 58, 493, 986
179 : 1, 179
178 : 1, 2, 89, 178
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 116,986,179,178,221, is 1.
Now, the common factors can be found like this.
116:2x 2x 29
986:2x 17x 29
179:179
178:2x 89
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 17x 29 = 1972
Therefore, the value for common factors is 1972.
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 = 805378832752/(1x1972)
LCM = 805378832752/1972
LCM = 408407116
Thus, we can understand that the LCM of 116,986,179,178,221 is 408407116.
