Find LCM of 774,905,615,243,873 with Prime Factorization
3 | 774, 905, 615, 243, 873 |
3 | 258, 905, 205, 81, 291 |
5 | 86, 905, 205, 27, 97 |
86, 181, 41, 27, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 86 x 181 x 41 x 27 x 97 = 75215768130
Therefore, the lowest common multiple of 774,905,615,243,873 is 75215768130.
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.
774 x 905 x 615 x 243 x 873 = 91387158277950
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
905 : 1, 5, 181, 905
615 : 1, 3, 5, 15, 41, 123, 205, 615
243 : 1, 3, 9, 27, 81, 243
873 : 1, 3, 9, 97, 291, 873
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,905,615,243,873, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
905:5x 181
615:3x 5x 41
243:3x 3x 3x 3x 3
873:3x 3x 97
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 3x 3x 5 = 1215
Therefore, the value for common factors is 1215.
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 = 91387158277950/(1x1215)
LCM = 91387158277950/1215
LCM = 75215768130
Thus, we can understand that the LCM of 774,905,615,243,873 is 75215768130.
