Given numbers are 628,990,224,237,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,990,224,237,243 is 37131605280.
Find LCM of 628,990,224,237,243 with Prime Factorization
| 2 | 628, 990, 224, 237, 243 |
| 2 | 314, 495, 112, 237, 243 |
| 3 | 157, 495, 56, 237, 243 |
| 3 | 157, 165, 56, 79, 81 |
| 157, 55, 56, 79, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 157 x 55 x 56 x 79 x 27 = 37131605280
Therefore, the lowest common multiple of 628,990,224,237,243 is 37131605280.
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.
628 x 990 x 224 x 237 x 243 = 8020426740480
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.
628 : 1, 2, 4, 157, 314, 628
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
237 : 1, 3, 79, 237
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,990,224,237,243, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
990:2x 3x 3x 5x 11
224:2x 2x 2x 2x 2x 7
237:3x 79
243:3x 3x 3x 3x 3
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 8020426740480/(1x216)
LCM = 8020426740480/216
LCM = 37131605280
Thus, we can understand that the LCM of 628,990,224,237,243 is 37131605280.
