Find LCM of 855,558,221,495,513 with Prime Factorization
| 3 | 855, 558, 221, 495, 513 |
| 3 | 285, 186, 221, 165, 171 |
| 5 | 95, 62, 221, 55, 57 |
| 19 | 19, 62, 221, 11, 57 |
| 1, 62, 221, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 1 x 62 x 221 x 11 x 3 = 386601930
Therefore, the lowest common multiple of 855,558,221,495,513 is 386601930.
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.
855 x 558 x 221 x 495 x 513 = 26774116662150
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
221 : 1, 13, 17, 221
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
513 : 1, 3, 9, 19, 27, 57, 171, 513
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,558,221,495,513, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
558:2x 3x 3x 31
221:13x 17
495:3x 3x 5x 11
513:3x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 3x 5x 19 = 69255
Therefore, the value for common factors is 69255.
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 = 26774116662150/(1x69255)
LCM = 26774116662150/69255
LCM = 386601930
Thus, we can understand that the LCM of 855,558,221,495,513 is 386601930.
