Given numbers are 391,871,369,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,871,369,851 is 4649679333.
Find LCM of 391,871,369,851 with Prime Factorization
| 23 | 391, 871, 369, 851 |
| 17, 871, 369, 37 |
Multiply the prime numbers at the bottom and the left side.
23 x 17 x 871 x 369 x 37 = 4649679333
Therefore, the lowest common multiple of 391,871,369,851 is 4649679333.
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.
391 x 871 x 369 x 851 = 106942624659
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.
391 : 1, 17, 23, 391
871 : 1, 13, 67, 871
369 : 1, 3, 9, 41, 123, 369
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,871,369,851, is 1.
Now, the common factors can be found like this.
391:17x 23
871:13x 67
369:3x 3x 41
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 106942624659/(1x23)
LCM = 106942624659/23
LCM = 4649679333
Thus, we can understand that the LCM of 391,871,369,851 is 4649679333.
