The LCM of 873,216,849,917,665 is 516541074840.
Find LCM of 873,216,849,917,665 with Prime Factorization
| 3 | 873, 216, 849, 917, 665 |
| 3 | 291, 72, 283, 917, 665 |
| 7 | 97, 24, 283, 917, 665 |
| 97, 24, 283, 131, 95 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 97 x 24 x 283 x 131 x 95 = 516541074840
Therefore, the lowest common multiple of 873,216,849,917,665 is 516541074840.
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.
873 x 216 x 849 x 917 x 665 = 97626263144760
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.
873 : 1, 3, 9, 97, 291, 873
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
849 : 1, 3, 283, 849
917 : 1, 7, 131, 917
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,216,849,917,665, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
216:2x 2x 2x 3x 3x 3
849:3x 283
917:7x 131
665:5x 7x 19
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 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 97626263144760/(1x189)
LCM = 97626263144760/189
LCM = 516541074840
Thus, we can understand that the LCM of 873,216,849,917,665 is 516541074840.
