The LCM of 615,319,865,471,913 is 442272205155.
Find LCM of 615,319,865,471,913 with Prime Factorization
| 3 | 615, 319, 865, 471, 913 |
| 5 | 205, 319, 865, 157, 913 |
| 11 | 41, 319, 173, 157, 913 |
| 41, 29, 173, 157, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 41 x 29 x 173 x 157 x 83 = 442272205155
Therefore, the lowest common multiple of 615,319,865,471,913 is 442272205155.
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.
615 x 319 x 865 x 471 x 913 = 72974913850575
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
319 : 1, 11, 29, 319
865 : 1, 5, 173, 865
471 : 1, 3, 157, 471
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,319,865,471,913, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
319:11x 29
865:5x 173
471:3x 157
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 72974913850575/(1x165)
LCM = 72974913850575/165
LCM = 442272205155
Thus, we can understand that the LCM of 615,319,865,471,913 is 442272205155.
