Find LCM of 351,381,646,353,162 with Prime Factorization
2 | 351, 381, 646, 353, 162 |
3 | 351, 381, 323, 353, 81 |
3 | 117, 127, 323, 353, 27 |
3 | 39, 127, 323, 353, 9 |
13, 127, 323, 353, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 127 x 323 x 353 x 3 = 30495749778
Therefore, the lowest common multiple of 351,381,646,353,162 is 30495749778.
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.
351 x 381 x 646 x 353 x 162 = 4940311464036
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
381 : 1, 3, 127, 381
646 : 1, 2, 17, 19, 34, 38, 323, 646
353 : 1, 353
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,381,646,353,162, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
381:3x 127
646:2x 17x 19
353:353
162:2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 4940311464036/(1x162)
LCM = 4940311464036/162
LCM = 30495749778
Thus, we can understand that the LCM of 351,381,646,353,162 is 30495749778.
