Given numbers are 491,115,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,115,180 is 2032740.
Find LCM of 491,115,180 with Prime Factorization
| 5 | 491, 115, 180 |
| 491, 23, 36 |
Multiply the prime numbers at the bottom and the left side.
5 x 491 x 23 x 36 = 2032740
Therefore, the lowest common multiple of 491,115,180 is 2032740.
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.
491 x 115 x 180 = 10163700
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.
491 : 1, 491
115 : 1, 5, 23, 115
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,115,180, is 1.
Now, the common factors can be found like this.
491:491
115:5x 23
180:2x 2x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 10163700/(1x5)
LCM = 10163700/5
LCM = 2032740
Thus, we can understand that the LCM of 491,115,180 is 2032740.
