Find LCM of 673,645,382,855,828 with Prime Factorization
2 | 673, 645, 382, 855, 828 |
3 | 673, 645, 191, 855, 414 |
3 | 673, 215, 191, 285, 138 |
5 | 673, 215, 191, 95, 46 |
673, 43, 191, 19, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 673 x 43 x 191 x 19 x 46 = 434781272340
Therefore, the lowest common multiple of 673,645,382,855,828 is 434781272340.
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.
673 x 645 x 382 x 855 x 828 = 117390943531800
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.
673 : 1, 673
645 : 1, 3, 5, 15, 43, 129, 215, 645
382 : 1, 2, 191, 382
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,645,382,855,828, is 1.
Now, the common factors can be found like this.
673:673
645:3x 5x 43
382:2x 191
855:3x 3x 5x 19
828:2x 2x 3x 3x 23
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 5 = 270
Therefore, the value for common factors is 270.
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 = 117390943531800/(1x270)
LCM = 117390943531800/270
LCM = 434781272340
Thus, we can understand that the LCM of 673,645,382,855,828 is 434781272340.
