Given numbers are 605,851,189,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,851,189,321 is 10411912665.
Find LCM of 605,851,189,321 with Prime Factorization
| 3 | 605, 851, 189, 321 |
| 605, 851, 63, 107 |
Multiply the prime numbers at the bottom and the left side.
3 x 605 x 851 x 63 x 107 = 10411912665
Therefore, the lowest common multiple of 605,851,189,321 is 10411912665.
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.
605 x 851 x 189 x 321 = 31235737995
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.
605 : 1, 5, 11, 55, 121, 605
851 : 1, 23, 37, 851
189 : 1, 3, 7, 9, 21, 27, 63, 189
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,851,189,321, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
851:23x 37
189:3x 3x 3x 7
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 31235737995/(1x3)
LCM = 31235737995/3
LCM = 10411912665
Thus, we can understand that the LCM of 605,851,189,321 is 10411912665.
