Find LCM of 243,665,532,686,929 with Prime Factorization
| 2 | 243, 665, 532, 686, 929 |
| 7 | 243, 665, 266, 343, 929 |
| 19 | 243, 95, 38, 49, 929 |
| 243, 5, 2, 49, 929 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 243 x 5 x 2 x 49 x 929 = 29423863980
Therefore, the lowest common multiple of 243,665,532,686,929 is 29423863980.
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.
243 x 665 x 532 x 686 x 929 = 54787234730760
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.
243 : 1, 3, 9, 27, 81, 243
665 : 1, 5, 7, 19, 35, 95, 133, 665
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
686 : 1, 2, 7, 14, 49, 98, 343, 686
929 : 1, 929
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,665,532,686,929, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
665:5x 7x 19
532:2x 2x 7x 19
686:2x 7x 7x 7
929:929
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 19 = 1862
Therefore, the value for common factors is 1862.
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 = 54787234730760/(1x1862)
LCM = 54787234730760/1862
LCM = 29423863980
Thus, we can understand that the LCM of 243,665,532,686,929 is 29423863980.
