Given numbers are 808,693,315,465
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,693,315,465 is 86791320.
Find LCM of 808,693,315,465 with Prime Factorization
3 | 808, 693, 315, 465 |
3 | 808, 231, 105, 155 |
5 | 808, 77, 35, 155 |
7 | 808, 77, 7, 31 |
808, 11, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 808 x 11 x 1 x 31 = 86791320
Therefore, the lowest common multiple of 808,693,315,465 is 86791320.
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.
808 x 693 x 315 x 465 = 82017797400
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,693,315,465, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
693:3x 3x 7x 11
315:3x 3x 5x 7
465:3x 5x 31
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 = 82017797400/(1x945)
LCM = 82017797400/945
LCM = 86791320
Thus, we can understand that the LCM of 808,693,315,465 is 86791320.
