Find LCM of 217,872,465,240,818 with Prime Factorization
| 2 | 217, 872, 465, 240, 818 |
| 2 | 217, 436, 465, 120, 409 |
| 2 | 217, 218, 465, 60, 409 |
| 3 | 217, 109, 465, 30, 409 |
| 5 | 217, 109, 155, 10, 409 |
| 31 | 217, 109, 31, 2, 409 |
| 7, 109, 1, 2, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 31 x 7 x 109 x 1 x 2 x 409 = 2321778480
Therefore, the lowest common multiple of 217,872,465,240,818 is 2321778480.
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.
217 x 872 x 465 x 240 x 818 = 17274031891200
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.
217 : 1, 7, 31, 217
872 : 1, 2, 4, 8, 109, 218, 436, 872
465 : 1, 3, 5, 15, 31, 93, 155, 465
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,872,465,240,818, is 1.
Now, the common factors can be found like this.
217:7x 31
872:2x 2x 2x 109
465:3x 5x 31
240:2x 2x 2x 2x 3x 5
818:2x 409
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 2x 2x 3x 5x 31 = 7440
Therefore, the value for common factors is 7440.
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 = 17274031891200/(1x7440)
LCM = 17274031891200/7440
LCM = 2321778480
Thus, we can understand that the LCM of 217,872,465,240,818 is 2321778480.
