Find LCM of 816,381,224,993 with Prime Factorization
| 2 | 816, 381, 224, 993 |
| 2 | 408, 381, 112, 993 |
| 2 | 204, 381, 56, 993 |
| 2 | 102, 381, 28, 993 |
| 3 | 51, 381, 14, 993 |
| 17, 127, 14, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 127 x 14 x 331 = 480230688
Therefore, the lowest common multiple of 816,381,224,993 is 480230688.
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 381 x 224 x 993 = 69153219072
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
381 : 1, 3, 127, 381
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,381,224,993, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
381:3x 127
224:2x 2x 2x 2x 2x 7
993:3x 331
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 3 = 144
Therefore, the value for common factors is 144.
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 = 69153219072/(1x144)
LCM = 69153219072/144
LCM = 480230688
Thus, we can understand that the LCM of 816,381,224,993 is 480230688.
