Given numbers are 843,735,442,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,735,442,197 is 17983828590.
Find LCM of 843,735,442,197 with Prime Factorization
| 3 | 843, 735, 442, 197 |
| 281, 245, 442, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 281 x 245 x 442 x 197 = 17983828590
Therefore, the lowest common multiple of 843,735,442,197 is 17983828590.
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.
843 x 735 x 442 x 197 = 53951485770
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.
843 : 1, 3, 281, 843
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
442 : 1, 2, 13, 17, 26, 34, 221, 442
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,735,442,197, is 1.
Now, the common factors can be found like this.
843:3x 281
735:3x 5x 7x 7
442:2x 13x 17
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 53951485770/(1x3)
LCM = 53951485770/3
LCM = 17983828590
Thus, we can understand that the LCM of 843,735,442,197 is 17983828590.
