Given numbers are 228,441,949,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,441,949,405 is 1431300780.
Find LCM of 228,441,949,405 with Prime Factorization
| 3 | 228, 441, 949, 405 |
| 3 | 76, 147, 949, 135 |
| 76, 49, 949, 45 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 76 x 49 x 949 x 45 = 1431300780
Therefore, the lowest common multiple of 228,441,949,405 is 1431300780.
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.
228 x 441 x 949 x 405 = 38645121060
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
949 : 1, 13, 73, 949
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,441,949,405, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
441:3x 3x 7x 7
949:13x 73
405:3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 38645121060/(1x27)
LCM = 38645121060/27
LCM = 1431300780
Thus, we can understand that the LCM of 228,441,949,405 is 1431300780.
