Find LCM of 842,731,374,243,909 with Prime Factorization
| 2 | 842, 731, 374, 243, 909 |
| 3 | 421, 731, 187, 243, 909 |
| 3 | 421, 731, 187, 81, 303 |
| 17 | 421, 731, 187, 27, 101 |
| 421, 43, 11, 27, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 421 x 43 x 11 x 27 x 101 = 166168921446
Therefore, the lowest common multiple of 842,731,374,243,909 is 166168921446.
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.
842 x 731 x 374 x 243 x 909 = 50847689962476
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.
842 : 1, 2, 421, 842
731 : 1, 17, 43, 731
374 : 1, 2, 11, 17, 22, 34, 187, 374
243 : 1, 3, 9, 27, 81, 243
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,731,374,243,909, is 1.
Now, the common factors can be found like this.
842:2x 421
731:17x 43
374:2x 11x 17
243:3x 3x 3x 3x 3
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 17 = 306
Therefore, the value for common factors is 306.
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 = 50847689962476/(1x306)
LCM = 50847689962476/306
LCM = 166168921446
Thus, we can understand that the LCM of 842,731,374,243,909 is 166168921446.
