Given numbers are 326,480,181,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,480,181,990 is 467327520.
Find LCM of 326,480,181,990 with Prime Factorization
2 | 326, 480, 181, 990 |
3 | 163, 240, 181, 495 |
5 | 163, 80, 181, 165 |
163, 16, 181, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 163 x 16 x 181 x 33 = 467327520
Therefore, the lowest common multiple of 326,480,181,990 is 467327520.
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.
326 x 480 x 181 x 990 = 28039651200
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.
326 : 1, 2, 163, 326
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
181 : 1, 181
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,480,181,990, is 1.
Now, the common factors can be found like this.
326:2x 163
480:2x 2x 2x 2x 2x 3x 5
181:181
990:2x 3x 3x 5x 11
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 5 = 60
Therefore, the value for common factors is 60.
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 = 28039651200/(1x60)
LCM = 28039651200/60
LCM = 467327520
Thus, we can understand that the LCM of 326,480,181,990 is 467327520.
