Given numbers are 228,193,966,945,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,193,966,945,938 is 21360201660.
Find LCM of 228,193,966,945,938 with Prime Factorization
| 2 | 228, 193, 966, 945, 938 |
| 3 | 114, 193, 483, 945, 469 |
| 7 | 38, 193, 161, 315, 469 |
| 38, 193, 23, 45, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 38 x 193 x 23 x 45 x 67 = 21360201660
Therefore, the lowest common multiple of 228,193,966,945,938 is 21360201660.
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 193 x 966 x 945 x 938 = 37679395728240
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
193 : 1, 193
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,193,966,945,938, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
193:193
966:2x 3x 7x 23
945:3x 3x 3x 5x 7
938:2x 7x 67
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 3x 3x 7x 7 = 1764
Therefore, the value for common factors is 1764.
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 = 37679395728240/(1x1764)
LCM = 37679395728240/1764
LCM = 21360201660
Thus, we can understand that the LCM of 228,193,966,945,938 is 21360201660.
