Given numbers are 897,855,621,927
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,855,621,927 is 78994305.
Find LCM of 897,855,621,927 with Prime Factorization
| 3 | 897, 855, 621, 927 |
| 3 | 299, 285, 207, 309 |
| 23 | 299, 95, 69, 103 |
| 13, 95, 3, 103 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 13 x 95 x 3 x 103 = 78994305
Therefore, the lowest common multiple of 897,855,621,927 is 78994305.
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.
897 x 855 x 621 x 927 = 441499170645
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
621 : 1, 3, 9, 23, 27, 69, 207, 621
927 : 1, 3, 9, 103, 309, 927
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,855,621,927, is 3.
Now, the common factors can be found like this.
897:3x 13x 23
855:3x 3x 5x 19
621:3x 3x 3x 23
927:3x 3x 103
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 3x 23 = 1863
Therefore, the value for common factors is 1863.
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 = 441499170645/(3x1863)
LCM = 441499170645/5589
LCM = 78994305
Thus, we can understand that the LCM of 897,855,621,927 is 78994305.
