Given numbers are 805,817,665,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,817,665,817 is 657685.
Find LCM of 805,817,665,817 with Prime Factorization
5 | 805, 817, 665, 817 |
7 | 161, 817, 133, 817 |
19 | 23, 817, 19, 817 |
43 | 23, 43, 1, 43 |
23, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 19 x 43 x 23 x 1 x 1 x 1 = 657685
Therefore, the lowest common multiple of 805,817,665,817 is 657685.
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.
805 x 817 x 665 x 817 = 357323548925
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
817 : 1, 19, 43, 817
665 : 1, 5, 7, 19, 35, 95, 133, 665
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,817,665,817, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
817:19x 43
665:5x 7x 19
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 19x 19x 43 = 543305
Therefore, the value for common factors is 543305.
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 = 357323548925/(1x543305)
LCM = 357323548925/543305
LCM = 657685
Thus, we can understand that the LCM of 805,817,665,817 is 657685.
