Find LCM of 173,627,561,105,663 with Prime Factorization
| 3 | 173, 627, 561, 105, 663 |
| 11 | 173, 209, 187, 35, 221 |
| 17 | 173, 19, 17, 35, 221 |
| 173, 19, 1, 35, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 173 x 19 x 1 x 35 x 13 = 839023185
Therefore, the lowest common multiple of 173,627,561,105,663 is 839023185.
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.
173 x 627 x 561 x 105 x 663 = 4236228061065
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.
173 : 1, 173
627 : 1, 3, 11, 19, 33, 57, 209, 627
561 : 1, 3, 11, 17, 33, 51, 187, 561
105 : 1, 3, 5, 7, 15, 21, 35, 105
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,627,561,105,663, is 1.
Now, the common factors can be found like this.
173:173
627:3x 11x 19
561:3x 11x 17
105:3x 5x 7
663:3x 13x 17
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 11x 17 = 5049
Therefore, the value for common factors is 5049.
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 = 4236228061065/(1x5049)
LCM = 4236228061065/5049
LCM = 839023185
Thus, we can understand that the LCM of 173,627,561,105,663 is 839023185.
