Given numbers are 701,579,171,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 701,579,171,855 is 115675515.
Find LCM of 701,579,171,855 with Prime Factorization
| 3 | 701, 579, 171, 855 |
| 3 | 701, 193, 57, 285 |
| 19 | 701, 193, 19, 95 |
| 701, 193, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 701 x 193 x 1 x 5 = 115675515
Therefore, the lowest common multiple of 701,579,171,855 is 115675515.
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.
701 x 579 x 171 x 855 = 59341539195
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.
701 : 1, 701
579 : 1, 3, 193, 579
171 : 1, 3, 9, 19, 57, 171
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,579,171,855, is 1.
Now, the common factors can be found like this.
701:701
579:3x 193
171:3x 3x 19
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 19 = 513
Therefore, the value for common factors is 513.
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 = 59341539195/(1x513)
LCM = 59341539195/513
LCM = 115675515
Thus, we can understand that the LCM of 701,579,171,855 is 115675515.
