Given numbers are 685,869,335,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,869,335,842 is 33581279710.
Find LCM of 685,869,335,842 with Prime Factorization
| 5 | 685, 869, 335, 842 |
| 137, 869, 67, 842 |
Multiply the prime numbers at the bottom and the left side.
5 x 137 x 869 x 67 x 842 = 33581279710
Therefore, the lowest common multiple of 685,869,335,842 is 33581279710.
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.
685 x 869 x 335 x 842 = 167906398550
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.
685 : 1, 5, 137, 685
869 : 1, 11, 79, 869
335 : 1, 5, 67, 335
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,869,335,842, is 1.
Now, the common factors can be found like this.
685:5x 137
869:11x 79
335:5x 67
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 167906398550/(1x5)
LCM = 167906398550/5
LCM = 33581279710
Thus, we can understand that the LCM of 685,869,335,842 is 33581279710.
