Find LCM of 621,240,200,218,256 with Prime Factorization
| 2 | 621, 240, 200, 218, 256 |
| 2 | 621, 120, 100, 109, 128 |
| 2 | 621, 60, 50, 109, 64 |
| 2 | 621, 30, 25, 109, 32 |
| 3 | 621, 15, 25, 109, 16 |
| 5 | 207, 5, 25, 109, 16 |
| 207, 1, 5, 109, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 207 x 1 x 5 x 109 x 16 = 433209600
Therefore, the lowest common multiple of 621,240,200,218,256 is 433209600.
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.
621 x 240 x 200 x 218 x 256 = 1663524864000
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
218 : 1, 2, 109, 218
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,240,200,218,256, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
240:2x 2x 2x 2x 3x 5
200:2x 2x 2x 5x 5
218:2x 109
256:2x 2x 2x 2x 2x 2x 2x 2
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 2x 2x 2x 3x 5 = 3840
Therefore, the value for common factors is 3840.
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 = 1663524864000/(1x3840)
LCM = 1663524864000/3840
LCM = 433209600
Thus, we can understand that the LCM of 621,240,200,218,256 is 433209600.
