Given numbers are 985,225,445,841
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,225,445,841 is 3317681925.
Find LCM of 985,225,445,841 with Prime Factorization
| 5 | 985, 225, 445, 841 |
| 197, 45, 89, 841 |
Multiply the prime numbers at the bottom and the left side.
5 x 197 x 45 x 89 x 841 = 3317681925
Therefore, the lowest common multiple of 985,225,445,841 is 3317681925.
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.
985 x 225 x 445 x 841 = 82942048125
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.
985 : 1, 5, 197, 985
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
445 : 1, 5, 89, 445
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,225,445,841, is 1.
Now, the common factors can be found like this.
985:5x 197
225:3x 3x 5x 5
445:5x 89
841:29x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 82942048125/(1x25)
LCM = 82942048125/25
LCM = 3317681925
Thus, we can understand that the LCM of 985,225,445,841 is 3317681925.
