Given numbers are 791,986,340,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,986,340,310 is 241777060.
Find LCM of 791,986,340,310 with Prime Factorization
| 2 | 791, 986, 340, 310 |
| 5 | 791, 493, 170, 155 |
| 17 | 791, 493, 34, 31 |
| 791, 29, 2, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 791 x 29 x 2 x 31 = 241777060
Therefore, the lowest common multiple of 791,986,340,310 is 241777060.
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.
791 x 986 x 340 x 310 = 82204200400
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.
791 : 1, 7, 113, 791
986 : 1, 2, 17, 29, 34, 58, 493, 986
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,986,340,310, is 1.
Now, the common factors can be found like this.
791:7x 113
986:2x 17x 29
340:2x 2x 5x 17
310:2x 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.
2x 2x 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 82204200400/(1x340)
LCM = 82204200400/340
LCM = 241777060
Thus, we can understand that the LCM of 791,986,340,310 is 241777060.
