Given numbers are 985,221,299,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,221,299,394 is 10013510.
Find LCM of 985,221,299,394 with Prime Factorization
13 | 985, 221, 299, 394 |
197 | 985, 17, 23, 394 |
5, 17, 23, 2 |
Multiply the prime numbers at the bottom and the left side.
13 x 197 x 5 x 17 x 23 x 2 = 10013510
Therefore, the lowest common multiple of 985,221,299,394 is 10013510.
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 221 x 299 x 394 = 25644599110
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
221 : 1, 13, 17, 221
299 : 1, 13, 23, 299
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,221,299,394, is 1.
Now, the common factors can be found like this.
985:5x 197
221:13x 17
299:13x 23
394:2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 197 = 2561
Therefore, the value for common factors is 2561.
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 = 25644599110/(1x2561)
LCM = 25644599110/2561
LCM = 10013510
Thus, we can understand that the LCM of 985,221,299,394 is 10013510.
