Given numbers are 321,842,618,775,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,842,618,775,939 is 6753056583450.
Find LCM of 321,842,618,775,939 with Prime Factorization
| 2 | 321, 842, 618, 775, 939 |
| 3 | 321, 421, 309, 775, 939 |
| 107, 421, 103, 775, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 421 x 103 x 775 x 313 = 6753056583450
Therefore, the lowest common multiple of 321,842,618,775,939 is 6753056583450.
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.
321 x 842 x 618 x 775 x 939 = 121555018502100
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.
321 : 1, 3, 107, 321
842 : 1, 2, 421, 842
618 : 1, 2, 3, 6, 103, 206, 309, 618
775 : 1, 5, 25, 31, 155, 775
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,842,618,775,939, is 1.
Now, the common factors can be found like this.
321:3x 107
842:2x 421
618:2x 3x 103
775:5x 5x 31
939:3x 313
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 = 121555018502100/(1x18)
LCM = 121555018502100/18
LCM = 6753056583450
Thus, we can understand that the LCM of 321,842,618,775,939 is 6753056583450.
