Given numbers are 437,665,779,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,665,779,399 is 1881285.
Find LCM of 437,665,779,399 with Prime Factorization
| 7 | 437, 665, 779, 399 |
| 19 | 437, 95, 779, 57 |
| 23, 5, 41, 3 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 23 x 5 x 41 x 3 = 1881285
Therefore, the lowest common multiple of 437,665,779,399 is 1881285.
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.
437 x 665 x 779 x 399 = 90326136705
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.
437 : 1, 19, 23, 437
665 : 1, 5, 7, 19, 35, 95, 133, 665
779 : 1, 19, 41, 779
399 : 1, 3, 7, 19, 21, 57, 133, 399
19 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,665,779,399, is 19.
Now, the common factors can be found like this.
437:19x 23
665:5x 7x 19
779:19x 41
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.
7x 19x 19 = 2527
Therefore, the value for common factors is 2527.
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 = 90326136705/(19x2527)
LCM = 90326136705/48013
LCM = 1881285
Thus, we can understand that the LCM of 437,665,779,399 is 1881285.
