Given numbers are 985,644,985,794
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,644,985,794 is 251832980.
Find LCM of 985,644,985,794 with Prime Factorization
| 2 | 985, 644, 985, 794 |
| 5 | 985, 322, 985, 397 |
| 197 | 197, 322, 197, 397 |
| 1, 322, 1, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 197 x 1 x 322 x 1 x 397 = 251832980
Therefore, the lowest common multiple of 985,644,985,794 is 251832980.
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 644 x 985 x 794 = 496110970600
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
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
985 : 1, 5, 197, 985
794 : 1, 2, 397, 794
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,644,985,794, is 1.
Now, the common factors can be found like this.
985:5x 197
644:2x 2x 7x 23
985:5x 197
794:2x 397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 197 = 1970
Therefore, the value for common factors is 1970.
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 = 496110970600/(1x1970)
LCM = 496110970600/1970
LCM = 251832980
Thus, we can understand that the LCM of 985,644,985,794 is 251832980.
