Find LCM of 648,378,836,882 with Prime Factorization
2 | 648, 378, 836, 882 |
2 | 324, 189, 418, 441 |
3 | 162, 189, 209, 441 |
3 | 54, 63, 209, 147 |
3 | 18, 21, 209, 49 |
7 | 6, 7, 209, 49 |
6, 1, 209, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 6 x 1 x 209 x 7 = 6636168
Therefore, the lowest common multiple of 648,378,836,882 is 6636168.
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.
648 x 378 x 836 x 882 = 180609948288
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,378,836,882, is 2.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
378:2x 3x 3x 3x 7
836:2x 2x 11x 19
882:2x 3x 3x 7x 7
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 3x 3x 7 = 13608
Therefore, the value for common factors is 13608.
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 = 180609948288/(2x13608)
LCM = 180609948288/27216
LCM = 6636168
Thus, we can understand that the LCM of 648,378,836,882 is 6636168.
