Given numbers are 969,125,855,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,125,855,441 is 17805375.
Find LCM of 969,125,855,441 with Prime Factorization
3 | 969, 125, 855, 441 |
3 | 323, 125, 285, 147 |
5 | 323, 125, 95, 49 |
19 | 323, 25, 19, 49 |
17, 25, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 17 x 25 x 1 x 49 = 17805375
Therefore, the lowest common multiple of 969,125,855,441 is 17805375.
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.
969 x 125 x 855 x 441 = 45670786875
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
125 : 1, 5, 25, 125
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,125,855,441, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
125:5x 5x 5
855:3x 3x 5x 19
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 19 = 2565
Therefore, the value for common factors is 2565.
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 = 45670786875/(1x2565)
LCM = 45670786875/2565
LCM = 17805375
Thus, we can understand that the LCM of 969,125,855,441 is 17805375.
