Given numbers are 653,949,855,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 653,949,855,247 is 529840935.
Find LCM of 653,949,855,247 with Prime Factorization
| 13 | 653, 949, 855, 247 |
| 19 | 653, 73, 855, 19 |
| 653, 73, 45, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 653 x 73 x 45 x 1 = 529840935
Therefore, the lowest common multiple of 653,949,855,247 is 529840935.
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.
653 x 949 x 855 x 247 = 130870710945
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.
653 : 1, 653
949 : 1, 13, 73, 949
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,949,855,247, is 1.
Now, the common factors can be found like this.
653:653
949:13x 73
855:3x 3x 5x 19
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 130870710945/(1x247)
LCM = 130870710945/247
LCM = 529840935
Thus, we can understand that the LCM of 653,949,855,247 is 529840935.
