Given numbers are 441,231,847,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 441,231,847,869 is 4215519.
Find LCM of 441,231,847,869 with Prime Factorization
| 3 | 441, 231, 847, 869 |
| 7 | 147, 77, 847, 869 |
| 11 | 21, 11, 121, 869 |
| 21, 1, 11, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 21 x 1 x 11 x 79 = 4215519
Therefore, the lowest common multiple of 441,231,847,869 is 4215519.
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.
441 x 231 x 847 x 869 = 74981436453
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
231 : 1, 3, 7, 11, 21, 33, 77, 231
847 : 1, 7, 11, 77, 121, 847
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,231,847,869, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
231:3x 7x 11
847:7x 11x 11
869:11x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 11x 11 = 17787
Therefore, the value for common factors is 17787.
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 = 74981436453/(1x17787)
LCM = 74981436453/17787
LCM = 4215519
Thus, we can understand that the LCM of 441,231,847,869 is 4215519.
