Given numbers are 531,458,474,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,458,474,399 is 2555281386.
Find LCM of 531,458,474,399 with Prime Factorization
| 2 | 531, 458, 474, 399 |
| 3 | 531, 229, 237, 399 |
| 177, 229, 79, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 177 x 229 x 79 x 133 = 2555281386
Therefore, the lowest common multiple of 531,458,474,399 is 2555281386.
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.
531 x 458 x 474 x 399 = 45995064948
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.
531 : 1, 3, 9, 59, 177, 531
458 : 1, 2, 229, 458
474 : 1, 2, 3, 6, 79, 158, 237, 474
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,458,474,399, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
458:2x 229
474:2x 3x 79
399:3x 7x 19
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 3 = 18
Therefore, the value for common factors is 18.
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 = 45995064948/(1x18)
LCM = 45995064948/18
LCM = 2555281386
Thus, we can understand that the LCM of 531,458,474,399 is 2555281386.
