Given numbers are 173,489,981,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 173,489,981,777 is 7164773721.
Find LCM of 173,489,981,777 with Prime Factorization
3 | 173, 489, 981, 777 |
173, 163, 327, 259 |
Multiply the prime numbers at the bottom and the left side.
3 x 173 x 163 x 327 x 259 = 7164773721
Therefore, the lowest common multiple of 173,489,981,777 is 7164773721.
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.
173 x 489 x 981 x 777 = 64482963489
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.
173 : 1, 173
489 : 1, 3, 163, 489
981 : 1, 3, 9, 109, 327, 981
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,489,981,777, is 1.
Now, the common factors can be found like this.
173:173
489:3x 163
981:3x 3x 109
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 64482963489/(1x9)
LCM = 64482963489/9
LCM = 7164773721
Thus, we can understand that the LCM of 173,489,981,777 is 7164773721.
