Find LCM of 189,104,952,312,391 with Prime Factorization
| 2 | 189, 104, 952, 312, 391 |
| 2 | 189, 52, 476, 156, 391 |
| 2 | 189, 26, 238, 78, 391 |
| 3 | 189, 13, 119, 39, 391 |
| 7 | 63, 13, 119, 13, 391 |
| 13 | 9, 13, 17, 13, 391 |
| 17 | 9, 1, 17, 1, 391 |
| 9, 1, 1, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 17 x 9 x 1 x 1 x 1 x 23 = 7685496
Therefore, the lowest common multiple of 189,104,952,312,391 is 7685496.
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.
189 x 104 x 952 x 312 x 391 = 2282776763904
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
104 : 1, 2, 4, 8, 13, 26, 52, 104
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,104,952,312,391, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
104:2x 2x 2x 13
952:2x 2x 2x 7x 17
312:2x 2x 2x 3x 13
391:17x 23
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 2x 3x 7x 13x 17 = 297024
Therefore, the value for common factors is 297024.
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 = 2282776763904/(1x297024)
LCM = 2282776763904/297024
LCM = 7685496
Thus, we can understand that the LCM of 189,104,952,312,391 is 7685496.
