Find LCM of 168,909,994,231,422 with Prime Factorization
2 | 168, 909, 994, 231, 422 |
3 | 84, 909, 497, 231, 211 |
7 | 28, 303, 497, 77, 211 |
4, 303, 71, 11, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 4 x 303 x 71 x 11 x 211 = 8388521064
Therefore, the lowest common multiple of 168,909,994,231,422 is 8388521064.
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 909 x 994 x 231 x 422 = 14797351156896
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
909 : 1, 3, 9, 101, 303, 909
994 : 1, 2, 7, 14, 71, 142, 497, 994
231 : 1, 3, 7, 11, 21, 33, 77, 231
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,909,994,231,422, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
909:3x 3x 101
994:2x 7x 71
231:3x 7x 11
422:2x 211
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 3x 3x 7x 7 = 1764
Therefore, the value for common factors is 1764.
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 = 14797351156896/(1x1764)
LCM = 14797351156896/1764
LCM = 8388521064
Thus, we can understand that the LCM of 168,909,994,231,422 is 8388521064.
