Given numbers are 502,165,642,961,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 502,165,642,961,909 is 2580699604230.
Find LCM of 502,165,642,961,909 with Prime Factorization
| 2 | 502, 165, 642, 961, 909 |
| 3 | 251, 165, 321, 961, 909 |
| 251, 55, 107, 961, 303 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 251 x 55 x 107 x 961 x 303 = 2580699604230
Therefore, the lowest common multiple of 502,165,642,961,909 is 2580699604230.
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.
502 x 165 x 642 x 961 x 909 = 46452592876140
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.
502 : 1, 2, 251, 502
165 : 1, 3, 5, 11, 15, 33, 55, 165
642 : 1, 2, 3, 6, 107, 214, 321, 642
961 : 1, 31, 961
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,165,642,961,909, is 1.
Now, the common factors can be found like this.
502:2x 251
165:3x 5x 11
642:2x 3x 107
961:31x 31
909:3x 3x 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 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 46452592876140/(1x18)
LCM = 46452592876140/18
LCM = 2580699604230
Thus, we can understand that the LCM of 502,165,642,961,909 is 2580699604230.
