Given numbers are 311,865,748,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,865,748,928 is 46683787040.
Find LCM of 311,865,748,928 with Prime Factorization
| 2 | 311, 865, 748, 928 |
| 2 | 311, 865, 374, 464 |
| 311, 865, 187, 232 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 311 x 865 x 187 x 232 = 46683787040
Therefore, the lowest common multiple of 311,865,748,928 is 46683787040.
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.
311 x 865 x 748 x 928 = 186735148160
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.
311 : 1, 311
865 : 1, 5, 173, 865
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
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 311,865,748,928, is 1.
Now, the common factors can be found like this.
311:311
865:5x 173
748:2x 2x 11x 17
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 2 = 4
Therefore, the value for common factors is 4.
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 = 186735148160/(1x4)
LCM = 186735148160/4
LCM = 46683787040
Thus, we can understand that the LCM of 311,865,748,928 is 46683787040.
