Given numbers are 671,790,845,163,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,790,845,163,243 is 3548380582890.
Find LCM of 671,790,845,163,243 with Prime Factorization
5 | 671, 790, 845, 163, 243 |
671, 158, 169, 163, 243 |
Multiply the prime numbers at the bottom and the left side.
5 x 671 x 158 x 169 x 163 x 243 = 3548380582890
Therefore, the lowest common multiple of 671,790,845,163,243 is 3548380582890.
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.
671 x 790 x 845 x 163 x 243 = 17741902914450
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.
671 : 1, 11, 61, 671
790 : 1, 2, 5, 10, 79, 158, 395, 790
845 : 1, 5, 13, 65, 169, 845
163 : 1, 163
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,790,845,163,243, is 1.
Now, the common factors can be found like this.
671:11x 61
790:2x 5x 79
845:5x 13x 13
163:163
243:3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 17741902914450/(1x5)
LCM = 17741902914450/5
LCM = 3548380582890
Thus, we can understand that the LCM of 671,790,845,163,243 is 3548380582890.
