Given numbers are 394,588,455,641,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,588,455,641,197 is 4826306940.
Find LCM of 394,588,455,641,197 with Prime Factorization
| 2 | 394, 588, 455, 641, 197 |
| 7 | 197, 294, 455, 641, 197 |
| 197 | 197, 42, 65, 641, 197 |
| 1, 42, 65, 641, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 197 x 1 x 42 x 65 x 641 x 1 = 4826306940
Therefore, the lowest common multiple of 394,588,455,641,197 is 4826306940.
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.
394 x 588 x 455 x 641 x 197 = 13310954540520
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.
394 : 1, 2, 197, 394
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
455 : 1, 5, 7, 13, 35, 65, 91, 455
641 : 1, 641
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,588,455,641,197, is 1.
Now, the common factors can be found like this.
394:2x 197
588:2x 2x 3x 7x 7
455:5x 7x 13
641:641
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 197 = 2758
Therefore, the value for common factors is 2758.
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 = 13310954540520/(1x2758)
LCM = 13310954540520/2758
LCM = 4826306940
Thus, we can understand that the LCM of 394,588,455,641,197 is 4826306940.
