Given numbers are 105,394,399,766,658
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,394,399,766,658 is 14149326030.
Find LCM of 105,394,399,766,658 with Prime Factorization
| 2 | 105, 394, 399, 766, 658 |
| 3 | 105, 197, 399, 383, 329 |
| 7 | 35, 197, 133, 383, 329 |
| 5, 197, 19, 383, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 5 x 197 x 19 x 383 x 47 = 14149326030
Therefore, the lowest common multiple of 105,394,399,766,658 is 14149326030.
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.
105 x 394 x 399 x 766 x 658 = 8319803705640
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
394 : 1, 2, 197, 394
399 : 1, 3, 7, 19, 21, 57, 133, 399
766 : 1, 2, 383, 766
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,394,399,766,658, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
394:2x 197
399:3x 7x 19
766:2x 383
658:2x 7x 47
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 8319803705640/(1x588)
LCM = 8319803705640/588
LCM = 14149326030
Thus, we can understand that the LCM of 105,394,399,766,658 is 14149326030.
