Given numbers are 843,738,389,778,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,738,389,778,195 is 5243552730.
Find LCM of 843,738,389,778,195 with Prime Factorization
| 2 | 843, 738, 389, 778, 195 |
| 3 | 843, 369, 389, 389, 195 |
| 389 | 281, 123, 389, 389, 65 |
| 281, 123, 1, 1, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 389 x 281 x 123 x 1 x 1 x 65 = 5243552730
Therefore, the lowest common multiple of 843,738,389,778,195 is 5243552730.
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 738 x 389 x 778 x 195 = 36715356215460
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
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
389 : 1, 389
778 : 1, 2, 389, 778
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,738,389,778,195, is 1.
Now, the common factors can be found like this.
843:3x 281
738:2x 3x 3x 41
389:389
778:2x 389
195:3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 389 = 7002
Therefore, the value for common factors is 7002.
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 = 36715356215460/(1x7002)
LCM = 36715356215460/7002
LCM = 5243552730
Thus, we can understand that the LCM of 843,738,389,778,195 is 5243552730.
