Find LCM of 805,182,209,286,280 with Prime Factorization
| 2 | 805, 182, 209, 286, 280 |
| 5 | 805, 91, 209, 143, 140 |
| 7 | 161, 91, 209, 143, 28 |
| 11 | 23, 13, 209, 143, 4 |
| 13 | 23, 13, 19, 13, 4 |
| 23, 1, 19, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 13 x 23 x 1 x 19 x 1 x 4 = 17497480
Therefore, the lowest common multiple of 805,182,209,286,280 is 17497480.
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.
805 x 182 x 209 x 286 x 280 = 2452096847200
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
182 : 1, 2, 7, 13, 14, 26, 91, 182
209 : 1, 11, 19, 209
286 : 1, 2, 11, 13, 22, 26, 143, 286
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,182,209,286,280, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
182:2x 7x 13
209:11x 19
286:2x 11x 13
280:2x 2x 2x 5x 7
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 5x 7x 7x 11x 13 = 140140
Therefore, the value for common factors is 140140.
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 = 2452096847200/(1x140140)
LCM = 2452096847200/140140
LCM = 17497480
Thus, we can understand that the LCM of 805,182,209,286,280 is 17497480.
