Given numbers are 793,117,122,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 793,117,122,768 is 1827072.
Find LCM of 793,117,122,768 with Prime Factorization
| 2 | 793, 117, 122, 768 |
| 3 | 793, 117, 61, 384 |
| 13 | 793, 39, 61, 128 |
| 61 | 61, 3, 61, 128 |
| 1, 3, 1, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 61 x 1 x 3 x 1 x 128 = 1827072
Therefore, the lowest common multiple of 793,117,122,768 is 1827072.
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.
793 x 117 x 122 x 768 = 8693208576
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.
793 : 1, 13, 61, 793
117 : 1, 3, 9, 13, 39, 117
122 : 1, 2, 61, 122
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,117,122,768, is 1.
Now, the common factors can be found like this.
793:13x 61
117:3x 3x 13
122:2x 61
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 61 = 4758
Therefore, the value for common factors is 4758.
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 = 8693208576/(1x4758)
LCM = 8693208576/4758
LCM = 1827072
Thus, we can understand that the LCM of 793,117,122,768 is 1827072.
