Given numbers are 180,860,939,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,860,939,686 is 830958660.
Find LCM of 180,860,939,686 with Prime Factorization
2 | 180, 860, 939, 686 |
2 | 90, 430, 939, 343 |
3 | 45, 215, 939, 343 |
5 | 15, 215, 313, 343 |
3, 43, 313, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 3 x 43 x 313 x 343 = 830958660
Therefore, the lowest common multiple of 180,860,939,686 is 830958660.
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.
180 x 860 x 939 x 686 = 99715039200
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
939 : 1, 3, 313, 939
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,860,939,686, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
860:2x 2x 5x 43
939:3x 313
686:2x 7x 7x 7
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 99715039200/(1x120)
LCM = 99715039200/120
LCM = 830958660
Thus, we can understand that the LCM of 180,860,939,686 is 830958660.
