Given numbers are 211,325,285,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,325,285,691 is 2700963525.
Find LCM of 211,325,285,691 with Prime Factorization
| 5 | 211, 325, 285, 691 |
| 211, 65, 57, 691 |
Multiply the prime numbers at the bottom and the left side.
5 x 211 x 65 x 57 x 691 = 2700963525
Therefore, the lowest common multiple of 211,325,285,691 is 2700963525.
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.
211 x 325 x 285 x 691 = 13504817625
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.
211 : 1, 211
325 : 1, 5, 13, 25, 65, 325
285 : 1, 3, 5, 15, 19, 57, 95, 285
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,325,285,691, is 1.
Now, the common factors can be found like this.
211:211
325:5x 5x 13
285:3x 5x 19
691:691
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 = 13504817625/(1x5)
LCM = 13504817625/5
LCM = 2700963525
Thus, we can understand that the LCM of 211,325,285,691 is 2700963525.
