Find LCM of 170,561,105,176,891 with Prime Factorization
2 | 170, 561, 105, 176, 891 |
3 | 85, 561, 105, 88, 891 |
5 | 85, 187, 35, 88, 297 |
11 | 17, 187, 7, 88, 297 |
17 | 17, 17, 7, 8, 27 |
1, 1, 7, 8, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 1 x 1 x 7 x 8 x 27 = 8482320
Therefore, the lowest common multiple of 170,561,105,176,891 is 8482320.
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.
170 x 561 x 105 x 176 x 891 = 1570331901600
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
561 : 1, 3, 11, 17, 33, 51, 187, 561
105 : 1, 3, 5, 7, 15, 21, 35, 105
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,561,105,176,891, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
561:3x 11x 17
105:3x 5x 7
176:2x 2x 2x 2x 11
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 11x 11x 17 = 185130
Therefore, the value for common factors is 185130.
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 = 1570331901600/(1x185130)
LCM = 1570331901600/185130
LCM = 8482320
Thus, we can understand that the LCM of 170,561,105,176,891 is 8482320.
