Find LCM of 816,949,221,330 with Prime Factorization
2 | 816, 949, 221, 330 |
3 | 408, 949, 221, 165 |
13 | 136, 949, 221, 55 |
17 | 136, 73, 17, 55 |
8, 73, 1, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 8 x 73 x 1 x 55 = 42591120
Therefore, the lowest common multiple of 816,949,221,330 is 42591120.
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.
816 x 949 x 221 x 330 = 56475825120
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
949 : 1, 13, 73, 949
221 : 1, 13, 17, 221
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,949,221,330, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
949:13x 73
221:13x 17
330:2x 3x 5x 11
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 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 56475825120/(1x1326)
LCM = 56475825120/1326
LCM = 42591120
Thus, we can understand that the LCM of 816,949,221,330 is 42591120.
