Given numbers are 291,105,457,315,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,105,457,315,309 is 1438254405.
Find LCM of 291,105,457,315,309 with Prime Factorization
3 | 291, 105, 457, 315, 309 |
5 | 97, 35, 457, 105, 103 |
7 | 97, 7, 457, 21, 103 |
97, 1, 457, 3, 103 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 97 x 1 x 457 x 3 x 103 = 1438254405
Therefore, the lowest common multiple of 291,105,457,315,309 is 1438254405.
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.
291 x 105 x 457 x 315 x 309 = 1359150412725
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.
291 : 1, 3, 97, 291
105 : 1, 3, 5, 7, 15, 21, 35, 105
457 : 1, 457
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,105,457,315,309, is 1.
Now, the common factors can be found like this.
291:3x 97
105:3x 5x 7
457:457
315:3x 3x 5x 7
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 7 = 945
Therefore, the value for common factors is 945.
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 = 1359150412725/(1x945)
LCM = 1359150412725/945
LCM = 1438254405
Thus, we can understand that the LCM of 291,105,457,315,309 is 1438254405.
