Given numbers are 790,140,386,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,140,386,343 is 104594420.
Find LCM of 790,140,386,343 with Prime Factorization
| 2 | 790, 140, 386, 343 |
| 5 | 395, 70, 193, 343 |
| 7 | 79, 14, 193, 343 |
| 79, 2, 193, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 79 x 2 x 193 x 49 = 104594420
Therefore, the lowest common multiple of 790,140,386,343 is 104594420.
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.
790 x 140 x 386 x 343 = 14643218800
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
386 : 1, 2, 193, 386
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,140,386,343, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
140:2x 2x 5x 7
386:2x 193
343:7x 7x 7
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 14643218800/(1x140)
LCM = 14643218800/140
LCM = 104594420
Thus, we can understand that the LCM of 790,140,386,343 is 104594420.
