Given numbers are 497,923,384,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,923,384,781 is 27291264.
Find LCM of 497,923,384,781 with Prime Factorization
71 | 497, 923, 384, 781 |
7, 13, 384, 11 |
Multiply the prime numbers at the bottom and the left side.
71 x 7 x 13 x 384 x 11 = 27291264
Therefore, the lowest common multiple of 497,923,384,781 is 27291264.
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.
497 x 923 x 384 x 781 = 137575261824
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.
497 : 1, 7, 71, 497
923 : 1, 13, 71, 923
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,923,384,781, is 1.
Now, the common factors can be found like this.
497:7x 71
923:13x 71
384:2x 2x 2x 2x 2x 2x 2x 3
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
71x 71 = 5041
Therefore, the value for common factors is 5041.
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 = 137575261824/(1x5041)
LCM = 137575261824/5041
LCM = 27291264
Thus, we can understand that the LCM of 497,923,384,781 is 27291264.
