Given numbers are 365,691,765,561,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 365,691,765,561,168 is 23770759320.
Find LCM of 365,691,765,561,168 with Prime Factorization
| 3 | 365, 691, 765, 561, 168 |
| 5 | 365, 691, 255, 187, 56 |
| 17 | 73, 691, 51, 187, 56 |
| 73, 691, 3, 11, 56 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 73 x 691 x 3 x 11 x 56 = 23770759320
Therefore, the lowest common multiple of 365,691,765,561,168 is 23770759320.
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.
365 x 691 x 765 x 561 x 168 = 18184630879800
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.
365 : 1, 5, 73, 365
691 : 1, 691
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
561 : 1, 3, 11, 17, 33, 51, 187, 561
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 365,691,765,561,168, is 1.
Now, the common factors can be found like this.
365:5x 73
691:691
765:3x 3x 5x 17
561:3x 11x 17
168:2x 2x 2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 17 = 765
Therefore, the value for common factors is 765.
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 = 18184630879800/(1x765)
LCM = 18184630879800/765
LCM = 23770759320
Thus, we can understand that the LCM of 365,691,765,561,168 is 23770759320.
