Given numbers are 642,211,211,235,244
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,211,211,235,244 is 3883695540.
Find LCM of 642,211,211,235,244 with Prime Factorization
2 | 642, 211, 211, 235, 244 |
211 | 321, 211, 211, 235, 122 |
321, 1, 1, 235, 122 |
Multiply the prime numbers at the bottom and the left side.
2 x 211 x 321 x 1 x 1 x 235 x 122 = 3883695540
Therefore, the lowest common multiple of 642,211,211,235,244 is 3883695540.
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.
642 x 211 x 211 x 235 x 244 = 1638919517880
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
211 : 1, 211
211 : 1, 211
235 : 1, 5, 47, 235
244 : 1, 2, 4, 61, 122, 244
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,211,211,235,244, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
211:211
211:211
235:5x 47
244:2x 2x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 211 = 422
Therefore, the value for common factors is 422.
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 = 1638919517880/(1x422)
LCM = 1638919517880/422
LCM = 3883695540
Thus, we can understand that the LCM of 642,211,211,235,244 is 3883695540.
