Given numbers are 168,289,282,662,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,289,282,662,665 is 71755729080.
Find LCM of 168,289,282,662,665 with Prime Factorization
| 2 | 168, 289, 282, 662, 665 |
| 3 | 84, 289, 141, 331, 665 |
| 7 | 28, 289, 47, 331, 665 |
| 4, 289, 47, 331, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 4 x 289 x 47 x 331 x 95 = 71755729080
Therefore, the lowest common multiple of 168,289,282,662,665 is 71755729080.
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.
168 x 289 x 282 x 662 x 665 = 6027481242720
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
289 : 1, 17, 289
282 : 1, 2, 3, 6, 47, 94, 141, 282
662 : 1, 2, 331, 662
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,289,282,662,665, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
289:17x 17
282:2x 3x 47
662:2x 331
665:5x 7x 19
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 6027481242720/(1x84)
LCM = 6027481242720/84
LCM = 71755729080
Thus, we can understand that the LCM of 168,289,282,662,665 is 71755729080.
