Given numbers are 428,225,411,424
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,225,411,424 is 1398468600.
Find LCM of 428,225,411,424 with Prime Factorization
| 2 | 428, 225, 411, 424 |
| 2 | 214, 225, 411, 212 |
| 3 | 107, 225, 411, 106 |
| 107, 75, 137, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 75 x 137 x 106 = 1398468600
Therefore, the lowest common multiple of 428,225,411,424 is 1398468600.
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.
428 x 225 x 411 x 424 = 16781623200
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.
428 : 1, 2, 4, 107, 214, 428
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
411 : 1, 3, 137, 411
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,225,411,424, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
225:3x 3x 5x 5
411:3x 137
424:2x 2x 2x 53
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 3 = 12
Therefore, the value for common factors is 12.
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 = 16781623200/(1x12)
LCM = 16781623200/12
LCM = 1398468600
Thus, we can understand that the LCM of 428,225,411,424 is 1398468600.
