Given numbers are 281,429,642,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,429,642,107 is 25797486.
Find LCM of 281,429,642,107 with Prime Factorization
3 | 281, 429, 642, 107 |
107 | 281, 143, 214, 107 |
281, 143, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 107 x 281 x 143 x 2 x 1 = 25797486
Therefore, the lowest common multiple of 281,429,642,107 is 25797486.
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.
281 x 429 x 642 x 107 = 8280993006
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.
281 : 1, 281
429 : 1, 3, 11, 13, 33, 39, 143, 429
642 : 1, 2, 3, 6, 107, 214, 321, 642
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,429,642,107, is 1.
Now, the common factors can be found like this.
281:281
429:3x 11x 13
642:2x 3x 107
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 107 = 321
Therefore, the value for common factors is 321.
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 = 8280993006/(1x321)
LCM = 8280993006/321
LCM = 25797486
Thus, we can understand that the LCM of 281,429,642,107 is 25797486.
