Given numbers are 222,282,921,451,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 222,282,921,451,945 is 455068006470.
Find LCM of 222,282,921,451,945 with Prime Factorization
| 2 | 222, 282, 921, 451, 945 |
| 3 | 111, 141, 921, 451, 945 |
| 37, 47, 307, 451, 315 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 47 x 307 x 451 x 315 = 455068006470
Therefore, the lowest common multiple of 222,282,921,451,945 is 455068006470.
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.
222 x 282 x 921 x 451 x 945 = 24573672349380
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.
222 : 1, 2, 3, 6, 37, 74, 111, 222
282 : 1, 2, 3, 6, 47, 94, 141, 282
921 : 1, 3, 307, 921
451 : 1, 11, 41, 451
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,282,921,451,945, is 1.
Now, the common factors can be found like this.
222:2x 3x 37
282:2x 3x 47
921:3x 307
451:11x 41
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 24573672349380/(1x54)
LCM = 24573672349380/54
LCM = 455068006470
Thus, we can understand that the LCM of 222,282,921,451,945 is 455068006470.
