Given numbers are 704,170,374,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 704,170,374,321 is 19208640.
Find LCM of 704,170,374,321 with Prime Factorization
| 2 | 704, 170, 374, 321 |
| 11 | 352, 85, 187, 321 |
| 17 | 32, 85, 17, 321 |
| 32, 5, 1, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 32 x 5 x 1 x 321 = 19208640
Therefore, the lowest common multiple of 704,170,374,321 is 19208640.
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.
704 x 170 x 374 x 321 = 14368062720
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
170 : 1, 2, 5, 10, 17, 34, 85, 170
374 : 1, 2, 11, 17, 22, 34, 187, 374
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,170,374,321, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
170:2x 5x 17
374:2x 11x 17
321:3x 107
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 14368062720/(1x748)
LCM = 14368062720/748
LCM = 19208640
Thus, we can understand that the LCM of 704,170,374,321 is 19208640.
