Given numbers are 11,57,31,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 11,57,31,242 is 427614.
Find LCM of 11,57,31,242 with Prime Factorization
| 11 | 11, 57, 31, 242 |
| 1, 57, 31, 22 |
Multiply the prime numbers at the bottom and the left side.
11 x 1 x 57 x 31 x 22 = 427614
Therefore, the lowest common multiple of 11,57,31,242 is 427614.
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.
11 x 57 x 31 x 242 = 4703754
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.
11 : 1, 11
57 : 1, 3, 19, 57
31 : 1, 31
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 11,57,31,242, is 1.
Now, the common factors can be found like this.
11:11
57:3x 19
31:31
242:2x 11x 11
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 = 4703754/(1x11)
LCM = 4703754/11
LCM = 427614
Thus, we can understand that the LCM of 11,57,31,242 is 427614.
