Given numbers are 205,638,500,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 205,638,500,744 is 1216347000.
Find LCM of 205,638,500,744 with Prime Factorization
| 2 | 205, 638, 500, 744 |
| 2 | 205, 319, 250, 372 |
| 5 | 205, 319, 125, 186 |
| 41, 319, 25, 186 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 319 x 25 x 186 = 1216347000
Therefore, the lowest common multiple of 205,638,500,744 is 1216347000.
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.
205 x 638 x 500 x 744 = 48653880000
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.
205 : 1, 5, 41, 205
638 : 1, 2, 11, 22, 29, 58, 319, 638
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,638,500,744, is 1.
Now, the common factors can be found like this.
205:5x 41
638:2x 11x 29
500:2x 2x 5x 5x 5
744:2x 2x 2x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 48653880000/(1x40)
LCM = 48653880000/40
LCM = 1216347000
Thus, we can understand that the LCM of 205,638,500,744 is 1216347000.
