Find LCM of 882,428,945,343 with Prime Factorization
2 | 882, 428, 945, 343 |
3 | 441, 214, 945, 343 |
3 | 147, 214, 315, 343 |
7 | 49, 214, 105, 343 |
7 | 7, 214, 15, 49 |
1, 214, 15, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 7 x 1 x 214 x 15 x 7 = 19818540
Therefore, the lowest common multiple of 882,428,945,343 is 19818540.
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 428 x 945 x 343 = 122359665960
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
428 : 1, 2, 4, 107, 214, 428
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,428,945,343, is 1.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
428:2x 2x 107
945:3x 3x 3x 5x 7
343:7x 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 3x 3x 7x 7x 7 = 6174
Therefore, the value for common factors is 6174.
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 = 122359665960/(1x6174)
LCM = 122359665960/6174
LCM = 19818540
Thus, we can understand that the LCM of 882,428,945,343 is 19818540.
