Given numbers are 805,175,789,115,911
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,175,789,115,911 is 2893085475.
Find LCM of 805,175,789,115,911 with Prime Factorization
| 5 | 805, 175, 789, 115, 911 |
| 7 | 161, 35, 789, 23, 911 |
| 23 | 23, 5, 789, 23, 911 |
| 1, 5, 789, 1, 911 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 1 x 5 x 789 x 1 x 911 = 2893085475
Therefore, the lowest common multiple of 805,175,789,115,911 is 2893085475.
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.
805 x 175 x 789 x 115 x 911 = 11644669036875
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
175 : 1, 5, 7, 25, 35, 175
789 : 1, 3, 263, 789
115 : 1, 5, 23, 115
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,175,789,115,911, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
175:5x 5x 7
789:3x 263
115:5x 23
911:911
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 23 = 4025
Therefore, the value for common factors is 4025.
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 = 11644669036875/(1x4025)
LCM = 11644669036875/4025
LCM = 2893085475
Thus, we can understand that the LCM of 805,175,789,115,911 is 2893085475.
