Find LCM of 855,276,412,660 with Prime Factorization
| 2 | 855, 276, 412, 660 |
| 2 | 855, 138, 206, 330 |
| 3 | 855, 69, 103, 165 |
| 5 | 285, 23, 103, 55 |
| 57, 23, 103, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 57 x 23 x 103 x 11 = 89121780
Therefore, the lowest common multiple of 855,276,412,660 is 89121780.
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 276 x 412 x 660 = 64167681600
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
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
412 : 1, 2, 4, 103, 206, 412
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,276,412,660, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
276:2x 2x 3x 23
412:2x 2x 103
660:2x 2x 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 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 64167681600/(1x720)
LCM = 64167681600/720
LCM = 89121780
Thus, we can understand that the LCM of 855,276,412,660 is 89121780.
