Given numbers are 989,401,163,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,401,163,815 is 323220035.
Find LCM of 989,401,163,815 with Prime Factorization
163 | 989, 401, 163, 815 |
989, 401, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
163 x 989 x 401 x 1 x 5 = 323220035
Therefore, the lowest common multiple of 989,401,163,815 is 323220035.
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.
989 x 401 x 163 x 815 = 52684865705
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.
989 : 1, 23, 43, 989
401 : 1, 401
163 : 1, 163
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,401,163,815, is 1.
Now, the common factors can be found like this.
989:23x 43
401:401
163:163
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
163 = 163
Therefore, the value for common factors is 163.
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 = 52684865705/(1x163)
LCM = 52684865705/163
LCM = 323220035
Thus, we can understand that the LCM of 989,401,163,815 is 323220035.
