Given numbers are 279,361,837,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,361,837,647 is 195495579.
Find LCM of 279,361,837,647 with Prime Factorization
| 3 | 279, 361, 837, 647 |
| 3 | 93, 361, 279, 647 |
| 31 | 31, 361, 93, 647 |
| 1, 361, 3, 647 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 31 x 1 x 361 x 3 x 647 = 195495579
Therefore, the lowest common multiple of 279,361,837,647 is 195495579.
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 361 x 837 x 647 = 54543266541
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
361 : 1, 19, 361
837 : 1, 3, 9, 27, 31, 93, 279, 837
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,361,837,647, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
361:19x 19
837:3x 3x 3x 31
647:647
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 31 = 279
Therefore, the value for common factors is 279.
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 = 54543266541/(1x279)
LCM = 54543266541/279
LCM = 195495579
Thus, we can understand that the LCM of 279,361,837,647 is 195495579.
