Given numbers are 251,644,965,872,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,644,965,872,808 is 3434509876280.
Find LCM of 251,644,965,872,808 with Prime Factorization
| 2 | 251, 644, 965, 872, 808 |
| 2 | 251, 322, 965, 436, 404 |
| 2 | 251, 161, 965, 218, 202 |
| 251, 161, 965, 109, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 251 x 161 x 965 x 109 x 101 = 3434509876280
Therefore, the lowest common multiple of 251,644,965,872,808 is 3434509876280.
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.
251 x 644 x 965 x 872 x 808 = 109904316040960
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.
251 : 1, 251
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
965 : 1, 5, 193, 965
872 : 1, 2, 4, 8, 109, 218, 436, 872
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,644,965,872,808, is 1.
Now, the common factors can be found like this.
251:251
644:2x 2x 7x 23
965:5x 193
872:2x 2x 2x 109
808:2x 2x 2x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 109904316040960/(1x32)
LCM = 109904316040960/32
LCM = 3434509876280
Thus, we can understand that the LCM of 251,644,965,872,808 is 3434509876280.
