Given numbers are 885,456,681,456
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 885,456,681,456 is 30536040.
Find LCM of 885,456,681,456 with Prime Factorization
| 2 | 885, 456, 681, 456 |
| 2 | 885, 228, 681, 228 |
| 2 | 885, 114, 681, 114 |
| 3 | 885, 57, 681, 57 |
| 19 | 295, 19, 227, 19 |
| 295, 1, 227, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 295 x 1 x 227 x 1 = 30536040
Therefore, the lowest common multiple of 885,456,681,456 is 30536040.
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.
885 x 456 x 681 x 456 = 125319908160
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.
885 : 1, 3, 5, 15, 59, 177, 295, 885
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
681 : 1, 3, 227, 681
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 885,456,681,456, is 3.
Now, the common factors can be found like this.
885:3x 5x 59
456:2x 2x 2x 3x 19
681:3x 227
456:2x 2x 2x 3x 19
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 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 125319908160/(3x1368)
LCM = 125319908160/4104
LCM = 30536040
Thus, we can understand that the LCM of 885,456,681,456 is 30536040.
