Find LCM of 864,444,972,711,687 with Prime Factorization
2 | 864, 444, 972, 711, 687 |
2 | 432, 222, 486, 711, 687 |
3 | 216, 111, 243, 711, 687 |
3 | 72, 37, 81, 237, 229 |
3 | 24, 37, 27, 79, 229 |
8, 37, 9, 79, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 8 x 37 x 9 x 79 x 229 = 5204997792
Therefore, the lowest common multiple of 864,444,972,711,687 is 5204997792.
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.
864 x 444 x 972 x 711 x 687 = 182133282737664
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
711 : 1, 3, 9, 79, 237, 711
687 : 1, 3, 229, 687
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,444,972,711,687, is 3.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
444:2x 2x 3x 37
972:2x 2x 3x 3x 3x 3x 3
711:3x 3x 79
687:3x 229
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 3x 3x 3x 3x 3x 3 = 11664
Therefore, the value for common factors is 11664.
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 = 182133282737664/(3x11664)
LCM = 182133282737664/34992
LCM = 5204997792
Thus, we can understand that the LCM of 864,444,972,711,687 is 5204997792.
