Find LCM of 821,816,768,954,773 with Prime Factorization
| 2 | 821, 816, 768, 954, 773 |
| 2 | 821, 408, 384, 477, 773 |
| 2 | 821, 204, 192, 477, 773 |
| 2 | 821, 102, 96, 477, 773 |
| 3 | 821, 51, 48, 477, 773 |

Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 821 x 17 x 16 x 159 x 773 = 1317437183232
Therefore, the lowest common multiple of 821,816,768,954,773 is 1317437183232.
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.
821 x 816 x 768 x 954 x 773 = 379421908770816
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.
821 : 1, 821
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
773 : 1, 773
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,816,768,954,773, is 1.
Now, the common factors can be found like this.
821:821
816:2x 2x 2x 2x 3x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
954:2x 3x 3x 53
773:773
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 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 379421908770816/(1x288)
LCM = 379421908770816/288
LCM = 1317437183232
Thus, we can understand that the LCM of 821,816,768,954,773 is 1317437183232.
