Find LCM of 729,891,676,742 with Prime Factorization
2 | 729, 891, 676, 742 |
3 | 729, 891, 338, 371 |
3 | 243, 297, 338, 371 |
3 | 81, 99, 338, 371 |
3 | 27, 33, 338, 371 |
9, 11, 338, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 9 x 11 x 338 x 371 = 2011133124
Therefore, the lowest common multiple of 729,891,676,742 is 2011133124.
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.
729 x 891 x 676 x 742 = 325803566088
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.
729 : 1, 3, 9, 27, 81, 243, 729
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,891,676,742, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
891:3x 3x 3x 3x 11
676:2x 2x 13x 13
742:2x 7x 53
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 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 325803566088/(1x162)
LCM = 325803566088/162
LCM = 2011133124
Thus, we can understand that the LCM of 729,891,676,742 is 2011133124.
