Find LCM of 480,561,388,690,911 with Prime Factorization
2 | 480, 561, 388, 690, 911 |
2 | 240, 561, 194, 345, 911 |
3 | 120, 561, 97, 345, 911 |
5 | 40, 187, 97, 115, 911 |
8, 187, 97, 23, 911 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 8 x 187 x 97 x 23 x 911 = 182431904160
Therefore, the lowest common multiple of 480,561,388,690,911 is 182431904160.
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.
480 x 561 x 388 x 690 x 911 = 65675485497600
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.
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
388 : 1, 2, 4, 97, 194, 388
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
911 : 1, 911
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 480,561,388,690,911, is 1.
Now, the common factors can be found like this.
480:2x 2x 2x 2x 2x 3x 5
561:3x 11x 17
388:2x 2x 97
690:2x 3x 5x 23
911:911
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 5 = 360
Therefore, the value for common factors is 360.
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 = 65675485497600/(1x360)
LCM = 65675485497600/360
LCM = 182431904160
Thus, we can understand that the LCM of 480,561,388,690,911 is 182431904160.
