Given numbers are 319,403,638,448
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,403,638,448 is 57593536.
Find LCM of 319,403,638,448 with Prime Factorization
| 2 | 319, 403, 638, 448 |
| 11 | 319, 403, 319, 224 |
| 29 | 29, 403, 29, 224 |
| 1, 403, 1, 224 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 1 x 403 x 1 x 224 = 57593536
Therefore, the lowest common multiple of 319,403,638,448 is 57593536.
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.
319 x 403 x 638 x 448 = 36744675968
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.
319 : 1, 11, 29, 319
403 : 1, 13, 31, 403
638 : 1, 2, 11, 22, 29, 58, 319, 638
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,403,638,448, is 1.
Now, the common factors can be found like this.
319:11x 29
403:13x 31
638:2x 11x 29
448:2x 2x 2x 2x 2x 2x 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 11x 29 = 638
Therefore, the value for common factors is 638.
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 = 36744675968/(1x638)
LCM = 36744675968/638
LCM = 57593536
Thus, we can understand that the LCM of 319,403,638,448 is 57593536.
