Given numbers are 686,567,851,806,352
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,567,851,806,352 is 3353948646048.
Find LCM of 686,567,851,806,352 with Prime Factorization
| 2 | 686, 567, 851, 806, 352 |
| 7 | 343, 567, 851, 403, 176 |
| 49, 81, 851, 403, 176 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 49 x 81 x 851 x 403 x 176 = 3353948646048
Therefore, the lowest common multiple of 686,567,851,806,352 is 3353948646048.
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 567 x 851 x 806 x 352 = 93910562089344
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
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
851 : 1, 23, 37, 851
806 : 1, 2, 13, 26, 31, 62, 403, 806
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,567,851,806,352, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
567:3x 3x 3x 3x 7
851:23x 37
806:2x 13x 31
352:2x 2x 2x 2x 2x 11
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 7 = 28
Therefore, the value for common factors is 28.
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 = 93910562089344/(1x28)
LCM = 93910562089344/28
LCM = 3353948646048
Thus, we can understand that the LCM of 686,567,851,806,352 is 3353948646048.
