Find LCM of 287,608,800,209 with Prime Factorization
2 | 287, 608, 800, 209 |
2 | 287, 304, 400, 209 |
2 | 287, 152, 200, 209 |
2 | 287, 76, 100, 209 |
2 | 287, 38, 50, 209 |
19 | 287, 19, 25, 209 |
287, 1, 25, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 19 x 287 x 1 x 25 x 11 = 47986400
Therefore, the lowest common multiple of 287,608,800,209 is 47986400.
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.
287 x 608 x 800 x 209 = 29175731200
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.
287 : 1, 7, 41, 287
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,608,800,209, is 1.
Now, the common factors can be found like this.
287:7x 41
608:2x 2x 2x 2x 2x 19
800:2x 2x 2x 2x 2x 5x 5
209:11x 19
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 2x 19 = 608
Therefore, the value for common factors is 608.
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 = 29175731200/(1x608)
LCM = 29175731200/608
LCM = 47986400
Thus, we can understand that the LCM of 287,608,800,209 is 47986400.
