Given numbers are 460,465,945,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 460,465,945,992 is 21561120.
Find LCM of 460,465,945,992 with Prime Factorization
| 2 | 460, 465, 945, 992 |
| 2 | 230, 465, 945, 496 |
| 3 | 115, 465, 945, 248 |
| 5 | 115, 155, 315, 248 |
| 31 | 23, 31, 63, 248 |
| 23, 1, 63, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 31 x 23 x 1 x 63 x 8 = 21561120
Therefore, the lowest common multiple of 460,465,945,992 is 21561120.
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.
460 x 465 x 945 x 992 = 200518416000
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
465 : 1, 3, 5, 15, 31, 93, 155, 465
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,465,945,992, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
465:3x 5x 31
945:3x 3x 3x 5x 7
992:2x 2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 5x 31 = 9300
Therefore, the value for common factors is 9300.
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 = 200518416000/(1x9300)
LCM = 200518416000/9300
LCM = 21561120
Thus, we can understand that the LCM of 460,465,945,992 is 21561120.
