Given numbers are 791,279,843,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,279,843,791 is 62013609.
Find LCM of 791,279,843,791 with Prime Factorization
| 3 | 791, 279, 843, 791 |
| 7 | 791, 93, 281, 791 |
| 113 | 113, 93, 281, 113 |
| 1, 93, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 113 x 1 x 93 x 281 x 1 = 62013609
Therefore, the lowest common multiple of 791,279,843,791 is 62013609.
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 279 x 843 x 791 = 147158294157
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
279 : 1, 3, 9, 31, 93, 279
843 : 1, 3, 281, 843
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,279,843,791, is 1.
Now, the common factors can be found like this.
791:7x 113
279:3x 3x 31
843:3x 281
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.
3x 7x 113 = 2373
Therefore, the value for common factors is 2373.
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 = 147158294157/(1x2373)
LCM = 147158294157/2373
LCM = 62013609
Thus, we can understand that the LCM of 791,279,843,791 is 62013609.
