Given numbers are 111,238,242,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,238,242,407 is 3196578.
Find LCM of 111,238,242,407 with Prime Factorization
| 2 | 111, 238, 242, 407 |
| 11 | 111, 119, 121, 407 |
| 37 | 111, 119, 11, 37 |
| 3, 119, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 37 x 3 x 119 x 11 x 1 = 3196578
Therefore, the lowest common multiple of 111,238,242,407 is 3196578.
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.
111 x 238 x 242 x 407 = 2602014492
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.
111 : 1, 3, 37, 111
238 : 1, 2, 7, 14, 17, 34, 119, 238
242 : 1, 2, 11, 22, 121, 242
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,238,242,407, is 1.
Now, the common factors can be found like this.
111:3x 37
238:2x 7x 17
242:2x 11x 11
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 37 = 814
Therefore, the value for common factors is 814.
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 = 2602014492/(1x814)
LCM = 2602014492/814
LCM = 3196578
Thus, we can understand that the LCM of 111,238,242,407 is 3196578.
