Given numbers are 388,195,455,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,195,455,668 is 88446540.
Find LCM of 388,195,455,668 with Prime Factorization
2 | 388, 195, 455, 668 |
2 | 194, 195, 455, 334 |
5 | 97, 195, 455, 167 |
13 | 97, 39, 91, 167 |
97, 3, 7, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 97 x 3 x 7 x 167 = 88446540
Therefore, the lowest common multiple of 388,195,455,668 is 88446540.
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 195 x 455 x 668 = 22996100400
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
195 : 1, 3, 5, 13, 15, 39, 65, 195
455 : 1, 5, 7, 13, 35, 65, 91, 455
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,195,455,668, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
195:3x 5x 13
455:5x 7x 13
668:2x 2x 167
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 22996100400/(1x260)
LCM = 22996100400/260
LCM = 88446540
Thus, we can understand that the LCM of 388,195,455,668 is 88446540.
