Find LCM of 646,176,986,551,187 with Prime Factorization
| 2 | 646, 176, 986, 551, 187 |
| 11 | 323, 88, 493, 551, 187 |
| 17 | 323, 8, 493, 551, 17 |
| 19 | 19, 8, 29, 551, 1 |
| 29 | 1, 8, 29, 29, 1 |
| 1, 8, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 19 x 29 x 1 x 8 x 1 x 1 x 1 = 1648592
Therefore, the lowest common multiple of 646,176,986,551,187 is 1648592.
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 176 x 986 x 551 x 187 = 11550886225472
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
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
986 : 1, 2, 17, 29, 34, 58, 493, 986
551 : 1, 19, 29, 551
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,176,986,551,187, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
176:2x 2x 2x 2x 11
986:2x 17x 29
551:19x 29
187:11x 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 11x 17x 17x 19x 29 = 7006516
Therefore, the value for common factors is 7006516.
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 = 11550886225472/(1x7006516)
LCM = 11550886225472/7006516
LCM = 1648592
Thus, we can understand that the LCM of 646,176,986,551,187 is 1648592.
