Given numbers are 615,578,556,696
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,578,556,696 is 5731598280.
Find LCM of 615,578,556,696 with Prime Factorization
| 2 | 615, 578, 556, 696 |
| 2 | 615, 289, 278, 348 |
| 3 | 615, 289, 139, 174 |
| 205, 289, 139, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 205 x 289 x 139 x 58 = 5731598280
Therefore, the lowest common multiple of 615,578,556,696 is 5731598280.
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.
615 x 578 x 556 x 696 = 137558358720
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
578 : 1, 2, 17, 34, 289, 578
556 : 1, 2, 4, 139, 278, 556
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,578,556,696, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
578:2x 17x 17
556:2x 2x 139
696:2x 2x 2x 3x 29
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 3 = 24
Therefore, the value for common factors is 24.
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 = 137558358720/(1x24)
LCM = 137558358720/24
LCM = 5731598280
Thus, we can understand that the LCM of 615,578,556,696 is 5731598280.
