Given numbers are 8210,9890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8210,9890 is 8119690.
Find LCM of 8210,9890 with Prime Factorization
| 2 | 8210, 9890 |
| 5 | 4105, 4945 |
| 821, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 821 x 989 = 8119690
Therefore, the lowest common multiple of 8210,9890 is 8119690.
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.
8210 x 9890 = 81196900
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.
8210 : 1, 2, 5, 10, 821, 1642, 4105, 8210
9890 : 1, 2, 5, 10, 23, 43, 46, 86, 115, 215, 230, 430, 989, 1978, 4945, 9890
10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8210,9890, is 10.
Now, the common factors can be found like this.
8210:2x 5x 821
9890:2x 5x 23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 81196900/(10x1)
LCM = 81196900/10
LCM = 8119690
Thus, we can understand that the LCM of 8210,9890 is 8119690.
