Given numbers are 454,447,403,531,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,447,403,531,390 is 72378852390.
Find LCM of 454,447,403,531,390 with Prime Factorization
2 | 454, 447, 403, 531, 390 |
3 | 227, 447, 403, 531, 195 |
13 | 227, 149, 403, 177, 65 |
227, 149, 31, 177, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 227 x 149 x 31 x 177 x 5 = 72378852390
Therefore, the lowest common multiple of 454,447,403,531,390 is 72378852390.
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.
454 x 447 x 403 x 531 x 390 = 16936651459260
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.
454 : 1, 2, 227, 454
447 : 1, 3, 149, 447
403 : 1, 13, 31, 403
531 : 1, 3, 9, 59, 177, 531
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,447,403,531,390, is 1.
Now, the common factors can be found like this.
454:2x 227
447:3x 149
403:13x 31
531:3x 3x 59
390:2x 3x 5x 13
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 13 = 234
Therefore, the value for common factors is 234.
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 = 16936651459260/(1x234)
LCM = 16936651459260/234
LCM = 72378852390
Thus, we can understand that the LCM of 454,447,403,531,390 is 72378852390.
