Given numbers are 279,620,713,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,620,713,809 is 103827060.
Find LCM of 279,620,713,809 with Prime Factorization
| 31 | 279, 620, 713, 809 |
| 9, 20, 23, 809 |
Multiply the prime numbers at the bottom and the left side.
31 x 9 x 20 x 23 x 809 = 103827060
Therefore, the lowest common multiple of 279,620,713,809 is 103827060.
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.
279 x 620 x 713 x 809 = 99777804660
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.
279 : 1, 3, 9, 31, 93, 279
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
713 : 1, 23, 31, 713
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,620,713,809, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
620:2x 2x 5x 31
713:23x 31
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31x 31 = 961
Therefore, the value for common factors is 961.
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 = 99777804660/(1x961)
LCM = 99777804660/961
LCM = 103827060
Thus, we can understand that the LCM of 279,620,713,809 is 103827060.
