Find LCM of 565,556,255,399,648 with Prime Factorization
| 2 | 565, 556, 255, 399, 648 |
| 2 | 565, 278, 255, 399, 324 |
| 3 | 565, 139, 255, 399, 162 |
| 5 | 565, 139, 85, 133, 54 |
| 113, 139, 17, 133, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 113 x 139 x 17 x 133 x 54 = 115063827480
Therefore, the lowest common multiple of 565,556,255,399,648 is 115063827480.
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.
565 x 556 x 255 x 399 x 648 = 20711488946400
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.
565 : 1, 5, 113, 565
556 : 1, 2, 4, 139, 278, 556
255 : 1, 3, 5, 15, 17, 51, 85, 255
399 : 1, 3, 7, 19, 21, 57, 133, 399
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,556,255,399,648, is 1.
Now, the common factors can be found like this.
565:5x 113
556:2x 2x 139
255:3x 5x 17
399:3x 7x 19
648:2x 2x 2x 3x 3x 3x 3
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 20711488946400/(1x180)
LCM = 20711488946400/180
LCM = 115063827480
Thus, we can understand that the LCM of 565,556,255,399,648 is 115063827480.
