Given numbers are 282,252,822,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,252,822,945 is 24339420.
Find LCM of 282,252,822,945 with Prime Factorization
| 2 | 282, 252, 822, 945 |
| 3 | 141, 126, 411, 945 |
| 3 | 47, 42, 137, 315 |
| 7 | 47, 14, 137, 105 |
| 47, 2, 137, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 47 x 2 x 137 x 15 = 24339420
Therefore, the lowest common multiple of 282,252,822,945 is 24339420.
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.
282 x 252 x 822 x 945 = 55201804560
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
822 : 1, 2, 3, 6, 137, 274, 411, 822
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,252,822,945, is 3.
Now, the common factors can be found like this.
282:2x 3x 47
252:2x 2x 3x 3x 7
822:2x 3x 137
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 2x 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 55201804560/(3x756)
LCM = 55201804560/2268
LCM = 24339420
Thus, we can understand that the LCM of 282,252,822,945 is 24339420.
