Given numbers are 455,923,231,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,923,231,947 is 1009563555.
Find LCM of 455,923,231,947 with Prime Factorization
| 7 | 455, 923, 231, 947 |
| 13 | 65, 923, 33, 947 |
| 5, 71, 33, 947 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 5 x 71 x 33 x 947 = 1009563555
Therefore, the lowest common multiple of 455,923,231,947 is 1009563555.
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.
455 x 923 x 231 x 947 = 91870283505
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
923 : 1, 13, 71, 923
231 : 1, 3, 7, 11, 21, 33, 77, 231
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,923,231,947, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
923:13x 71
231:3x 7x 11
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.
7x 13 = 91
Therefore, the value for common factors is 91.
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 = 91870283505/(1x91)
LCM = 91870283505/91
LCM = 1009563555
Thus, we can understand that the LCM of 455,923,231,947 is 1009563555.
