Given numbers are 309,961,925,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,961,925,395 is 21699548175.
Find LCM of 309,961,925,395 with Prime Factorization
| 5 | 309, 961, 925, 395 |
| 309, 961, 185, 79 |
Multiply the prime numbers at the bottom and the left side.
5 x 309 x 961 x 185 x 79 = 21699548175
Therefore, the lowest common multiple of 309,961,925,395 is 21699548175.
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.
309 x 961 x 925 x 395 = 108497740875
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.
309 : 1, 3, 103, 309
961 : 1, 31, 961
925 : 1, 5, 25, 37, 185, 925
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,961,925,395, is 1.
Now, the common factors can be found like this.
309:3x 103
961:31x 31
925:5x 5x 37
395:5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 108497740875/(1x5)
LCM = 108497740875/5
LCM = 21699548175
Thus, we can understand that the LCM of 309,961,925,395 is 21699548175.
