The LCM of 912,304,404,320 is 1842240.
Find LCM of 912,304,404,320 with Prime Factorization
| 2 | 912, 304, 404, 320 |
| 2 | 456, 152, 202, 160 |
| 2 | 228, 76, 101, 80 |
| 2 | 114, 38, 101, 40 |
| 19 | 57, 19, 101, 20 |
| 3, 1, 101, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 19 x 3 x 1 x 101 x 20 = 1842240
Therefore, the lowest common multiple of 912,304,404,320 is 1842240.
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.
912 x 304 x 404 x 320 = 35842621440
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
404 : 1, 2, 4, 101, 202, 404
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,304,404,320, is 4.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
304:2x 2x 2x 2x 19
404:2x 2x 101
320:2x 2x 2x 2x 2x 2x 5
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 19 = 4864
Therefore, the value for common factors is 4864.
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 = 35842621440/(4x4864)
LCM = 35842621440/19456
LCM = 1842240
Thus, we can understand that the LCM of 912,304,404,320 is 1842240.
