Find LCM of 168,916,864,649,861 with Prime Factorization
2 | 168, 916, 864, 649, 861 |
2 | 84, 458, 432, 649, 861 |
2 | 42, 229, 216, 649, 861 |
3 | 21, 229, 108, 649, 861 |
7 | 7, 229, 36, 649, 287 |
1, 229, 36, 649, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 1 x 229 x 36 x 649 x 41 = 36853252128
Therefore, the lowest common multiple of 168,916,864,649,861 is 36853252128.
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 916 x 864 x 649 x 861 = 74296156290048
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
916 : 1, 2, 4, 229, 458, 916
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
649 : 1, 11, 59, 649
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,916,864,649,861, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
916:2x 2x 229
864:2x 2x 2x 2x 2x 3x 3x 3
649:11x 59
861:3x 7x 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 2x 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 74296156290048/(1x2016)
LCM = 74296156290048/2016
LCM = 36853252128
Thus, we can understand that the LCM of 168,916,864,649,861 is 36853252128.
