The LCM of 429,694,615,223,819 is 285821425890.
Find LCM of 429,694,615,223,819 with Prime Factorization
| 3 | 429, 694, 615, 223, 819 |
| 13 | 143, 694, 205, 223, 273 |
| 11, 694, 205, 223, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 11 x 694 x 205 x 223 x 21 = 285821425890
Therefore, the lowest common multiple of 429,694,615,223,819 is 285821425890.
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.
429 x 694 x 615 x 223 x 819 = 33441106829130
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
694 : 1, 2, 347, 694
615 : 1, 3, 5, 15, 41, 123, 205, 615
223 : 1, 223
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,694,615,223,819, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
694:2x 347
615:3x 5x 41
223:223
819:3x 3x 7x 13
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 13 = 117
Therefore, the value for common factors is 117.
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 = 33441106829130/(1x117)
LCM = 33441106829130/117
LCM = 285821425890
Thus, we can understand that the LCM of 429,694,615,223,819 is 285821425890.
