Given numbers are 521,957,897,978,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,957,897,978,161 is 340201707846.
Find LCM of 521,957,897,978,161 with Prime Factorization
| 3 | 521, 957, 897, 978, 161 |
| 23 | 521, 319, 299, 326, 161 |
| 521, 319, 13, 326, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 521 x 319 x 13 x 326 x 7 = 340201707846
Therefore, the lowest common multiple of 521,957,897,978,161 is 340201707846.
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.
521 x 957 x 897 x 978 x 161 = 70421753524122
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.
521 : 1, 521
957 : 1, 3, 11, 29, 33, 87, 319, 957
897 : 1, 3, 13, 23, 39, 69, 299, 897
978 : 1, 2, 3, 6, 163, 326, 489, 978
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,957,897,978,161, is 1.
Now, the common factors can be found like this.
521:521
957:3x 11x 29
897:3x 13x 23
978:2x 3x 163
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 70421753524122/(1x207)
LCM = 70421753524122/207
LCM = 340201707846
Thus, we can understand that the LCM of 521,957,897,978,161 is 340201707846.
