Given numbers are 195,338,800,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 195,338,800,691 is 280269600.
Find LCM of 195,338,800,691 with Prime Factorization
| 2 | 195, 338, 800, 691 |
| 5 | 195, 169, 400, 691 |
| 13 | 39, 169, 80, 691 |
| 3, 13, 80, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 3 x 13 x 80 x 691 = 280269600
Therefore, the lowest common multiple of 195,338,800,691 is 280269600.
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.
195 x 338 x 800 x 691 = 36435048000
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
338 : 1, 2, 13, 26, 169, 338
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,338,800,691, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
338:2x 13x 13
800:2x 2x 2x 2x 2x 5x 5
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 36435048000/(1x130)
LCM = 36435048000/130
LCM = 280269600
Thus, we can understand that the LCM of 195,338,800,691 is 280269600.
