Given numbers are 715,295,521,521,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,295,521,521,805 is 3538519985.
Find LCM of 715,295,521,521,805 with Prime Factorization
5 | 715, 295, 521, 521, 805 |
521 | 143, 59, 521, 521, 161 |
143, 59, 1, 1, 161 |
Multiply the prime numbers at the bottom and the left side.
5 x 521 x 143 x 59 x 1 x 1 x 161 = 3538519985
Therefore, the lowest common multiple of 715,295,521,521,805 is 3538519985.
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.
715 x 295 x 521 x 521 x 805 = 46089222804625
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
295 : 1, 5, 59, 295
521 : 1, 521
521 : 1, 521
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,295,521,521,805, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
295:5x 59
521:521
521:521
805:5x 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.
5x 5x 521 = 13025
Therefore, the value for common factors is 13025.
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 = 46089222804625/(1x13025)
LCM = 46089222804625/13025
LCM = 3538519985
Thus, we can understand that the LCM of 715,295,521,521,805 is 3538519985.
