17 | 97, 8, 17, 323, 1 |
97, 8, 1, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 13 x 17 x 97 x 8 x 1 x 19 x 1 = 351909792
Therefore, the lowest common multiple of 388,864,442,646,702 is 351909792.
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.
388 x 864 x 442 x 646 x 702 = 67195063323648
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.
388 : 1, 2, 4, 97, 194, 388
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
442 : 1, 2, 13, 17, 26, 34, 221, 442
646 : 1, 2, 17, 19, 34, 38, 323, 646
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,864,442,646,702, is 2.
Now, the common factors can be found like this.
388:2x 2x 97
864:2x 2x 2x 2x 2x 3x 3x 3
442:2x 13x 17
646:2x 17x 19
702:2x 3x 3x 3x 13
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 3x 13x 17 = 95472
Therefore, the value for common factors is 95472.
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 = 67195063323648/(2x95472)
LCM = 67195063323648/190944
LCM = 351909792
Thus, we can understand that the LCM of 388,864,442,646,702 is 351909792.
