Find LCM of 882,381,108,644 with Prime Factorization
| 2 | 882, 381, 108, 644 |
| 2 | 441, 381, 54, 322 |
| 3 | 441, 381, 27, 161 |
| 3 | 147, 127, 9, 161 |
| 7 | 49, 127, 3, 161 |
| 7, 127, 3, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 7 x 127 x 3 x 23 = 15457932
Therefore, the lowest common multiple of 882,381,108,644 is 15457932.
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.
882 x 381 x 108 x 644 = 23372393184
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
381 : 1, 3, 127, 381
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,381,108,644, is 1.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
381:3x 127
108:2x 2x 3x 3x 3
644:2x 2x 7x 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 3x 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 23372393184/(1x1512)
LCM = 23372393184/1512
LCM = 15457932
Thus, we can understand that the LCM of 882,381,108,644 is 15457932.
