Given numbers are 363,817,979,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 363,817,979,820 is 21643751580.
Find LCM of 363,817,979,820 with Prime Factorization
11 | 363, 817, 979, 820 |
33, 817, 89, 820 |
Multiply the prime numbers at the bottom and the left side.
11 x 33 x 817 x 89 x 820 = 21643751580
Therefore, the lowest common multiple of 363,817,979,820 is 21643751580.
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.
363 x 817 x 979 x 820 = 238081267380
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.
363 : 1, 3, 11, 33, 121, 363
817 : 1, 19, 43, 817
979 : 1, 11, 89, 979
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,817,979,820, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
817:19x 43
979:11x 89
820:2x 2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 238081267380/(1x11)
LCM = 238081267380/11
LCM = 21643751580
Thus, we can understand that the LCM of 363,817,979,820 is 21643751580.
