Given numbers are 819,841,197,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,841,197,638 is 2985168186.
Find LCM of 819,841,197,638 with Prime Factorization
29 | 819, 841, 197, 638 |
819, 29, 197, 22 |
Multiply the prime numbers at the bottom and the left side.
29 x 819 x 29 x 197 x 22 = 2985168186
Therefore, the lowest common multiple of 819,841,197,638 is 2985168186.
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.
819 x 841 x 197 x 638 = 86569877394
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
841 : 1, 29, 841
197 : 1, 197
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,841,197,638, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
841:29x 29
197:197
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29 = 29
Therefore, the value for common factors is 29.
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 = 86569877394/(1x29)
LCM = 86569877394/29
LCM = 2985168186
Thus, we can understand that the LCM of 819,841,197,638 is 2985168186.
