Given numbers are 855,808,390,278,797
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,808,390,278,797 is 994933260360.
Find LCM of 855,808,390,278,797 with Prime Factorization
| 2 | 855, 808, 390, 278, 797 |
| 3 | 855, 404, 195, 139, 797 |
| 5 | 285, 404, 65, 139, 797 |
| 57, 404, 13, 139, 797 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 57 x 404 x 13 x 139 x 797 = 994933260360
Therefore, the lowest common multiple of 855,808,390,278,797 is 994933260360.
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 808 x 390 x 278 x 797 = 59695995621600
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
808 : 1, 2, 4, 8, 101, 202, 404, 808
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
278 : 1, 2, 139, 278
797 : 1, 797
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,808,390,278,797, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
808:2x 2x 2x 101
390:2x 3x 5x 13
278:2x 139
797:797
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 5 = 60
Therefore, the value for common factors is 60.
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 = 59695995621600/(1x60)
LCM = 59695995621600/60
LCM = 994933260360
Thus, we can understand that the LCM of 855,808,390,278,797 is 994933260360.
