Given numbers are 683,197,414,561,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 683,197,414,561,644 is 145833370452.
Find LCM of 683,197,414,561,644 with Prime Factorization
| 2 | 683, 197, 414, 561, 644 |
| 3 | 683, 197, 207, 561, 322 |
| 23 | 683, 197, 69, 187, 322 |
| 683, 197, 3, 187, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 683 x 197 x 3 x 187 x 14 = 145833370452
Therefore, the lowest common multiple of 683,197,414,561,644 is 145833370452.
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.
683 x 197 x 414 x 561 x 644 = 20125005122376
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.
683 : 1, 683
197 : 1, 197
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
561 : 1, 3, 11, 17, 33, 51, 187, 561
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 683,197,414,561,644, is 1.
Now, the common factors can be found like this.
683:683
197:197
414:2x 3x 3x 23
561:3x 11x 17
644:2x 2x 7x 23
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 23 = 138
Therefore, the value for common factors is 138.
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 = 20125005122376/(1x138)
LCM = 20125005122376/138
LCM = 145833370452
Thus, we can understand that the LCM of 683,197,414,561,644 is 145833370452.
