Find LCM of 686,153,382,765,725 with Prime Factorization
2 | 686, 153, 382, 765, 725 |
3 | 343, 153, 191, 765, 725 |
3 | 343, 51, 191, 255, 725 |
5 | 343, 17, 191, 85, 725 |
17 | 343, 17, 191, 17, 145 |
343, 1, 191, 1, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 343 x 1 x 191 x 1 x 145 = 14534059050
Therefore, the lowest common multiple of 686,153,382,765,725 is 14534059050.
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.
686 x 153 x 382 x 765 x 725 = 22237110346500
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
153 : 1, 3, 9, 17, 51, 153
382 : 1, 2, 191, 382
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,153,382,765,725, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
153:3x 3x 17
382:2x 191
765:3x 3x 5x 17
725:5x 5x 29
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 5x 17 = 1530
Therefore, the value for common factors is 1530.
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 = 22237110346500/(1x1530)
LCM = 22237110346500/1530
LCM = 14534059050
Thus, we can understand that the LCM of 686,153,382,765,725 is 14534059050.
