Given numbers are 897,979,604,842,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,979,604,842,621 is 2009725202628.
Find LCM of 897,979,604,842,621 with Prime Factorization
| 2 | 897, 979, 604, 842, 621 |
| 3 | 897, 979, 302, 421, 621 |
| 23 | 299, 979, 302, 421, 207 |
| 13, 979, 302, 421, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 13 x 979 x 302 x 421 x 9 = 2009725202628
Therefore, the lowest common multiple of 897,979,604,842,621 is 2009725202628.
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.
897 x 979 x 604 x 842 x 621 = 277342077962664
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
979 : 1, 11, 89, 979
604 : 1, 2, 4, 151, 302, 604
842 : 1, 2, 421, 842
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,979,604,842,621, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
979:11x 89
604:2x 2x 151
842:2x 421
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 277342077962664/(1x138)
LCM = 277342077962664/138
LCM = 2009725202628
Thus, we can understand that the LCM of 897,979,604,842,621 is 2009725202628.
