Given numbers are 107,642,407,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,642,407,121 is 2874234.
Find LCM of 107,642,407,121 with Prime Factorization
| 11 | 107, 642, 407, 121 |
| 107 | 107, 642, 37, 11 |
| 1, 6, 37, 11 |
Multiply the prime numbers at the bottom and the left side.
11 x 107 x 1 x 6 x 37 x 11 = 2874234
Therefore, the lowest common multiple of 107,642,407,121 is 2874234.
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.
107 x 642 x 407 x 121 = 3382973418
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.
107 : 1, 107
642 : 1, 2, 3, 6, 107, 214, 321, 642
407 : 1, 11, 37, 407
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,642,407,121, is 1.
Now, the common factors can be found like this.
107:107
642:2x 3x 107
407:11x 37
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 107 = 1177
Therefore, the value for common factors is 1177.
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 = 3382973418/(1x1177)
LCM = 3382973418/1177
LCM = 2874234
Thus, we can understand that the LCM of 107,642,407,121 is 2874234.
