Given numbers are 897,405,410,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,405,410,947 is 9403511130.
Find LCM of 897,405,410,947 with Prime Factorization
| 3 | 897, 405, 410, 947 |
| 5 | 299, 135, 410, 947 |
| 299, 27, 82, 947 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 299 x 27 x 82 x 947 = 9403511130
Therefore, the lowest common multiple of 897,405,410,947 is 9403511130.
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 405 x 410 x 947 = 141052666950
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
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
410 : 1, 2, 5, 10, 41, 82, 205, 410
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,405,410,947, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
405:3x 3x 3x 3x 5
410:2x 5x 41
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 141052666950/(1x15)
LCM = 141052666950/15
LCM = 9403511130
Thus, we can understand that the LCM of 897,405,410,947 is 9403511130.
