Given numbers are 340,249,510,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 340,249,510,790 is 6688140.
Find LCM of 340,249,510,790 with Prime Factorization
| 2 | 340, 249, 510, 790 |
| 3 | 170, 249, 255, 395 |
| 5 | 170, 83, 85, 395 |
| 17 | 34, 83, 17, 79 |
| 2, 83, 1, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 2 x 83 x 1 x 79 = 6688140
Therefore, the lowest common multiple of 340,249,510,790 is 6688140.
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.
340 x 249 x 510 x 790 = 34109514000
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
249 : 1, 3, 83, 249
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,249,510,790, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
249:3x 83
510:2x 3x 5x 17
790:2x 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.
2x 2x 3x 5x 5x 17 = 5100
Therefore, the value for common factors is 5100.
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 = 34109514000/(1x5100)
LCM = 34109514000/5100
LCM = 6688140
Thus, we can understand that the LCM of 340,249,510,790 is 6688140.
