Find LCM of 698,715,990,702,845 with Prime Factorization
2 | 698, 715, 990, 702, 845 |
3 | 349, 715, 495, 351, 845 |
3 | 349, 715, 165, 117, 845 |
5 | 349, 715, 55, 39, 845 |
11 | 349, 143, 11, 39, 169 |
13 | 349, 13, 1, 39, 169 |
349, 1, 1, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 13 x 349 x 1 x 1 x 3 x 13 = 175173570
Therefore, the lowest common multiple of 698,715,990,702,845 is 175173570.
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.
698 x 715 x 990 x 702 x 845 = 293082899967000
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.
698 : 1, 2, 349, 698
715 : 1, 5, 11, 13, 55, 65, 143, 715
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,715,990,702,845, is 1.
Now, the common factors can be found like this.
698:2x 349
715:5x 11x 13
990:2x 3x 3x 5x 11
702:2x 3x 3x 3x 13
845:5x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5x 5x 11x 13x 13 = 1673100
Therefore, the value for common factors is 1673100.
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 = 293082899967000/(1x1673100)
LCM = 293082899967000/1673100
LCM = 175173570
Thus, we can understand that the LCM of 698,715,990,702,845 is 175173570.
