The LCM of 304,656,861,928 is 15181152.
Find LCM of 304,656,861,928 with Prime Factorization
| 2 | 304, 656, 861, 928 |
| 2 | 152, 328, 861, 464 |
| 2 | 76, 164, 861, 232 |
| 2 | 38, 82, 861, 116 |
| 41 | 19, 41, 861, 58 |
| 19, 1, 21, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 41 x 19 x 1 x 21 x 58 = 15181152
Therefore, the lowest common multiple of 304,656,861,928 is 15181152.
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.
304 x 656 x 861 x 928 = 159341371392
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.
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
861 : 1, 3, 7, 21, 41, 123, 287, 861
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,656,861,928, is 1.
Now, the common factors can be found like this.
304:2x 2x 2x 2x 19
656:2x 2x 2x 2x 41
861:3x 7x 41
928:2x 2x 2x 2x 2x 29
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 41 = 10496
Therefore, the value for common factors is 10496.
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 = 159341371392/(1x10496)
LCM = 159341371392/10496
LCM = 15181152
Thus, we can understand that the LCM of 304,656,861,928 is 15181152.
