Find LCM of 816,824,849,561 with Prime Factorization
2 | 816, 824, 849, 561 |
2 | 408, 412, 849, 561 |
2 | 204, 206, 849, 561 |
3 | 102, 103, 849, 561 |
17 | 34, 103, 283, 187 |
2, 103, 283, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 2 x 103 x 283 x 11 = 261641424
Therefore, the lowest common multiple of 816,824,849,561 is 261641424.
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 824 x 849 x 561 = 320249102976
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
824 : 1, 2, 4, 8, 103, 206, 412, 824
849 : 1, 3, 283, 849
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,824,849,561, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
824:2x 2x 2x 103
849:3x 283
561:3x 11x 17
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 17 = 1224
Therefore, the value for common factors is 1224.
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 = 320249102976/(1x1224)
LCM = 320249102976/1224
LCM = 261641424
Thus, we can understand that the LCM of 816,824,849,561 is 261641424.
