Given numbers are 171,893,579,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,893,579,705 is 7755705.
Find LCM of 171,893,579,705 with Prime Factorization
| 3 | 171, 893, 579, 705 |
| 19 | 57, 893, 193, 235 |
| 47 | 3, 47, 193, 235 |
| 3, 1, 193, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 47 x 3 x 1 x 193 x 5 = 7755705
Therefore, the lowest common multiple of 171,893,579,705 is 7755705.
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.
171 x 893 x 579 x 705 = 62332601085
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.
171 : 1, 3, 9, 19, 57, 171
893 : 1, 19, 47, 893
579 : 1, 3, 193, 579
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,893,579,705, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
893:19x 47
579:3x 193
705:3x 5x 47
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 19x 47 = 8037
Therefore, the value for common factors is 8037.
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 = 62332601085/(1x8037)
LCM = 62332601085/8037
LCM = 7755705
Thus, we can understand that the LCM of 171,893,579,705 is 7755705.
