Given numbers are 860,869,783,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,869,783,395 is 585167220.
Find LCM of 860,869,783,395 with Prime Factorization
| 5 | 860, 869, 783, 395 |
| 79 | 172, 869, 783, 79 |
| 172, 11, 783, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 79 x 172 x 11 x 783 x 1 = 585167220
Therefore, the lowest common multiple of 860,869,783,395 is 585167220.
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.
860 x 869 x 783 x 395 = 231141051900
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
869 : 1, 11, 79, 869
783 : 1, 3, 9, 27, 29, 87, 261, 783
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,869,783,395, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
869:11x 79
783:3x 3x 3x 29
395:5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 79 = 395
Therefore, the value for common factors is 395.
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 = 231141051900/(1x395)
LCM = 231141051900/395
LCM = 585167220
Thus, we can understand that the LCM of 860,869,783,395 is 585167220.
