The LCM of 450,978,208,540 is 22885200.
Find LCM of 450,978,208,540 with Prime Factorization
2 | 450, 978, 208, 540 |
2 | 225, 489, 104, 270 |
3 | 225, 489, 52, 135 |
3 | 75, 163, 52, 45 |
5 | 25, 163, 52, 15 |
5, 163, 52, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 5 x 163 x 52 x 3 = 22885200
Therefore, the lowest common multiple of 450,978,208,540 is 22885200.
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.
450 x 978 x 208 x 540 = 49432032000
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.
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
978 : 1, 2, 3, 6, 163, 326, 489, 978
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,978,208,540, is 2.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
978:2x 3x 163
208:2x 2x 2x 2x 13
540:2x 2x 3x 3x 3x 5
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 2x 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 49432032000/(2x1080)
LCM = 49432032000/2160
LCM = 22885200
Thus, we can understand that the LCM of 450,978,208,540 is 22885200.
