Given numbers are 333,256,744,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 333,256,744,638 is 843017472.
Find LCM of 333,256,744,638 with Prime Factorization
| 2 | 333, 256, 744, 638 |
| 2 | 333, 128, 372, 319 |
| 2 | 333, 64, 186, 319 |
| 3 | 333, 32, 93, 319 |
| 111, 32, 31, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 111 x 32 x 31 x 319 = 843017472
Therefore, the lowest common multiple of 333,256,744,638 is 843017472.
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.
333 x 256 x 744 x 638 = 40464838656
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.
333 : 1, 3, 9, 37, 111, 333
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 333,256,744,638, is 1.
Now, the common factors can be found like this.
333:3x 3x 37
256:2x 2x 2x 2x 2x 2x 2x 2
744:2x 2x 2x 3x 31
638:2x 11x 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 3 = 48
Therefore, the value for common factors is 48.
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 = 40464838656/(1x48)
LCM = 40464838656/48
LCM = 843017472
Thus, we can understand that the LCM of 333,256,744,638 is 843017472.
