The LCM of 231,785,968,860 is 686171640.
Find LCM of 231,785,968,860 with Prime Factorization
| 2 | 231, 785, 968, 860 |
| 2 | 231, 785, 484, 430 |
| 5 | 231, 785, 242, 215 |
| 11 | 231, 157, 242, 43 |
| 21, 157, 22, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 21 x 157 x 22 x 43 = 686171640
Therefore, the lowest common multiple of 231,785,968,860 is 686171640.
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.
231 x 785 x 968 x 860 = 150957760800
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
785 : 1, 5, 157, 785
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,785,968,860, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
785:5x 157
968:2x 2x 2x 11x 11
860:2x 2x 5x 43
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 150957760800/(1x220)
LCM = 150957760800/220
LCM = 686171640
Thus, we can understand that the LCM of 231,785,968,860 is 686171640.
