Given numbers are 689,379,777,995,999
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,379,777,995,999 is 1816958637585.
Find LCM of 689,379,777,995,999 with Prime Factorization
| 3 | 689, 379, 777, 995, 999 |
| 37 | 689, 379, 259, 995, 333 |
| 689, 379, 7, 995, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 689 x 379 x 7 x 995 x 9 = 1816958637585
Therefore, the lowest common multiple of 689,379,777,995,999 is 1816958637585.
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.
689 x 379 x 777 x 995 x 999 = 201682408771935
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.
689 : 1, 13, 53, 689
379 : 1, 379
777 : 1, 3, 7, 21, 37, 111, 259, 777
995 : 1, 5, 199, 995
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,379,777,995,999, is 1.
Now, the common factors can be found like this.
689:13x 53
379:379
777:3x 7x 37
995:5x 199
999:3x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 37 = 111
Therefore, the value for common factors is 111.
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 = 201682408771935/(1x111)
LCM = 201682408771935/111
LCM = 1816958637585
Thus, we can understand that the LCM of 689,379,777,995,999 is 1816958637585.
