Find LCM of 168,981,718,872,123 with Prime Factorization
2 | 168, 981, 718, 872, 123 |
2 | 84, 981, 359, 436, 123 |
2 | 42, 981, 359, 218, 123 |
3 | 21, 981, 359, 109, 123 |
109 | 7, 327, 359, 109, 41 |
7, 3, 359, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 109 x 7 x 3 x 359 x 1 x 41 = 808602984
Therefore, the lowest common multiple of 168,981,718,872,123 is 808602984.
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.
168 x 981 x 718 x 872 x 123 = 12691832436864
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
981 : 1, 3, 9, 109, 327, 981
718 : 1, 2, 359, 718
872 : 1, 2, 4, 8, 109, 218, 436, 872
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,981,718,872,123, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
981:3x 3x 109
718:2x 359
872:2x 2x 2x 109
123:3x 41
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 2x 2x 3x 3x 109 = 15696
Therefore, the value for common factors is 15696.
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 = 12691832436864/(1x15696)
LCM = 12691832436864/15696
LCM = 808602984
Thus, we can understand that the LCM of 168,981,718,872,123 is 808602984.
