Given numbers are 280,359,795,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,359,795,791 is 1806042840.
Find LCM of 280,359,795,791 with Prime Factorization
| 5 | 280, 359, 795, 791 |
| 7 | 56, 359, 159, 791 |
| 8, 359, 159, 113 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 8 x 359 x 159 x 113 = 1806042840
Therefore, the lowest common multiple of 280,359,795,791 is 1806042840.
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.
280 x 359 x 795 x 791 = 63211499400
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
359 : 1, 359
795 : 1, 3, 5, 15, 53, 159, 265, 795
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,359,795,791, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
359:359
795:3x 5x 53
791:7x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 63211499400/(1x35)
LCM = 63211499400/35
LCM = 1806042840
Thus, we can understand that the LCM of 280,359,795,791 is 1806042840.
