Given numbers are 263,221,789,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 263,221,789,678 is 39407394.
Find LCM of 263,221,789,678 with Prime Factorization
| 3 | 263, 221, 789, 678 |
| 263 | 263, 221, 263, 226 |
| 1, 221, 1, 226 |
Multiply the prime numbers at the bottom and the left side.
3 x 263 x 1 x 221 x 1 x 226 = 39407394
Therefore, the lowest common multiple of 263,221,789,678 is 39407394.
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.
263 x 221 x 789 x 678 = 31092433866
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.
263 : 1, 263
221 : 1, 13, 17, 221
789 : 1, 3, 263, 789
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,221,789,678, is 1.
Now, the common factors can be found like this.
263:263
221:13x 17
789:3x 263
678:2x 3x 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 263 = 789
Therefore, the value for common factors is 789.
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 = 31092433866/(1x789)
LCM = 31092433866/789
LCM = 39407394
Thus, we can understand that the LCM of 263,221,789,678 is 39407394.
