Find LCM of 449,570,231,210,728 with Prime Factorization
| 2 | 449, 570, 231, 210, 728 |
| 3 | 449, 285, 231, 105, 364 |
| 5 | 449, 95, 77, 35, 364 |
| 7 | 449, 19, 77, 7, 364 |
| 449, 19, 11, 1, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 449 x 19 x 11 x 1 x 52 = 1024743720
Therefore, the lowest common multiple of 449,570,231,210,728 is 1024743720.
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.
449 x 570 x 231 x 210 x 728 = 9038239610400
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.
449 : 1, 449
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
231 : 1, 3, 7, 11, 21, 33, 77, 231
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,570,231,210,728, is 1.
Now, the common factors can be found like this.
449:449
570:2x 3x 5x 19
231:3x 7x 11
210:2x 3x 5x 7
728:2x 2x 2x 7x 13
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 5x 7x 7 = 8820
Therefore, the value for common factors is 8820.
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 = 9038239610400/(1x8820)
LCM = 9038239610400/8820
LCM = 1024743720
Thus, we can understand that the LCM of 449,570,231,210,728 is 1024743720.
