Given numbers are 521,845,845,694
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,845,845,694 is 305530030.
Find LCM of 521,845,845,694 with Prime Factorization
| 5 | 521, 845, 845, 694 |
| 13 | 521, 169, 169, 694 |
| 13 | 521, 13, 13, 694 |
| 521, 1, 1, 694 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 13 x 521 x 1 x 1 x 694 = 305530030
Therefore, the lowest common multiple of 521,845,845,694 is 305530030.
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 845 x 845 x 694 = 258172875350
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
845 : 1, 5, 13, 65, 169, 845
845 : 1, 5, 13, 65, 169, 845
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,845,845,694, is 1.
Now, the common factors can be found like this.
521:521
845:5x 13x 13
845:5x 13x 13
694:2x 347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 13 = 845
Therefore, the value for common factors is 845.
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 = 258172875350/(1x845)
LCM = 258172875350/845
LCM = 305530030
Thus, we can understand that the LCM of 521,845,845,694 is 305530030.
