Find LCM of 647,266,539,913,646 with Prime Factorization
2 | 647, 266, 539, 913, 646 |
7 | 647, 133, 539, 913, 323 |
11 | 647, 19, 77, 913, 323 |
19 | 647, 19, 7, 83, 323 |
647, 1, 7, 83, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 19 x 647 x 1 x 7 x 83 x 17 = 18698365994
Therefore, the lowest common multiple of 647,266,539,913,646 is 18698365994.
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.
647 x 266 x 539 x 913 x 646 = 54711418898444
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.
647 : 1, 647
266 : 1, 2, 7, 14, 19, 38, 133, 266
539 : 1, 7, 11, 49, 77, 539
913 : 1, 11, 83, 913
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,266,539,913,646, is 1.
Now, the common factors can be found like this.
647:647
266:2x 7x 19
539:7x 7x 11
913:11x 83
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 19 = 2926
Therefore, the value for common factors is 2926.
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 = 54711418898444/(1x2926)
LCM = 54711418898444/2926
LCM = 18698365994
Thus, we can understand that the LCM of 647,266,539,913,646 is 18698365994.
