Given numbers are 808,255,697,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,255,697,686 is 2897540520.
Find LCM of 808,255,697,686 with Prime Factorization
2 | 808, 255, 697, 686 |
17 | 404, 255, 697, 343 |
404, 15, 41, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 404 x 15 x 41 x 343 = 2897540520
Therefore, the lowest common multiple of 808,255,697,686 is 2897540520.
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.
808 x 255 x 697 x 686 = 98516377680
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
255 : 1, 3, 5, 15, 17, 51, 85, 255
697 : 1, 17, 41, 697
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,255,697,686, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
255:3x 5x 17
697:17x 41
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 98516377680/(1x34)
LCM = 98516377680/34
LCM = 2897540520
Thus, we can understand that the LCM of 808,255,697,686 is 2897540520.
