Given numbers are 646,387,164,722,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,387,164,722,908 is 88417207332.
Find LCM of 646,387,164,722,908 with Prime Factorization
2 | 646, 387, 164, 722, 908 |
2 | 323, 387, 82, 361, 454 |
19 | 323, 387, 41, 361, 227 |
17, 387, 41, 19, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 17 x 387 x 41 x 19 x 227 = 88417207332
Therefore, the lowest common multiple of 646,387,164,722,908 is 88417207332.
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.
646 x 387 x 164 x 722 x 908 = 26878831028928
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
387 : 1, 3, 9, 43, 129, 387
164 : 1, 2, 4, 41, 82, 164
722 : 1, 2, 19, 38, 361, 722
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,387,164,722,908, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
387:3x 3x 43
164:2x 2x 41
722:2x 19x 19
908:2x 2x 227
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 19 = 304
Therefore, the value for common factors is 304.
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 = 26878831028928/(1x304)
LCM = 26878831028928/304
LCM = 88417207332
Thus, we can understand that the LCM of 646,387,164,722,908 is 88417207332.
