Find LCM of 240,815,615,171,516 with Prime Factorization
| 2 | 240, 815, 615, 171, 516 |
| 2 | 120, 815, 615, 171, 258 |
| 3 | 60, 815, 615, 171, 129 |
| 5 | 20, 815, 205, 57, 43 |
| 4, 163, 41, 57, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 4 x 163 x 41 x 57 x 43 = 3931207920
Therefore, the lowest common multiple of 240,815,615,171,516 is 3931207920.
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.
240 x 815 x 615 x 171 x 516 = 10614261384000
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
815 : 1, 5, 163, 815
615 : 1, 3, 5, 15, 41, 123, 205, 615
171 : 1, 3, 9, 19, 57, 171
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,815,615,171,516, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
815:5x 163
615:3x 5x 41
171:3x 3x 19
516:2x 2x 3x 43
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 3x 5x 5 = 2700
Therefore, the value for common factors is 2700.
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 = 10614261384000/(1x2700)
LCM = 10614261384000/2700
LCM = 3931207920
Thus, we can understand that the LCM of 240,815,615,171,516 is 3931207920.
