Given numbers are 211,561,641,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,561,641,451 is 3110908251.
Find LCM of 211,561,641,451 with Prime Factorization
| 11 | 211, 561, 641, 451 |
| 211, 51, 641, 41 |
Multiply the prime numbers at the bottom and the left side.
11 x 211 x 51 x 641 x 41 = 3110908251
Therefore, the lowest common multiple of 211,561,641,451 is 3110908251.
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 561 x 641 x 451 = 34219990761
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
641 : 1, 641
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,561,641,451, is 1.
Now, the common factors can be found like this.
211:211
561:3x 11x 17
641:641
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 34219990761/(1x11)
LCM = 34219990761/11
LCM = 3110908251
Thus, we can understand that the LCM of 211,561,641,451 is 3110908251.
