Find LCM of 855,861,188,369,287 with Prime Factorization
| 3 | 855, 861, 188, 369, 287 |
| 3 | 285, 287, 188, 123, 287 |
| 7 | 95, 287, 188, 41, 287 |
| 41 | 95, 41, 188, 41, 41 |
| 95, 1, 188, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 41 x 95 x 1 x 188 x 1 x 1 = 46132380
Therefore, the lowest common multiple of 855,861,188,369,287 is 46132380.
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 861 x 188 x 369 x 287 = 14656672317420
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
188 : 1, 2, 4, 47, 94, 188
369 : 1, 3, 9, 41, 123, 369
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,861,188,369,287, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
861:3x 7x 41
188:2x 2x 47
369:3x 3x 41
287:7x 41
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 7x 41x 41 = 317709
Therefore, the value for common factors is 317709.
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 = 14656672317420/(1x317709)
LCM = 14656672317420/317709
LCM = 46132380
Thus, we can understand that the LCM of 855,861,188,369,287 is 46132380.
