Given numbers are 805,161,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,161,956 is 769580.
Find LCM of 805,161,956 with Prime Factorization
| 7 | 805, 161, 956 |
| 23 | 115, 23, 956 |
| 5, 1, 956 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 5 x 1 x 956 = 769580
Therefore, the lowest common multiple of 805,161,956 is 769580.
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 161 x 956 = 123902380
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
161 : 1, 7, 23, 161
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,161,956, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
161:7x 23
956:2x 2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 123902380/(1x161)
LCM = 123902380/161
LCM = 769580
Thus, we can understand that the LCM of 805,161,956 is 769580.
