Given numbers are 479,117,867,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 479,117,867,221 is 16196427.
Find LCM of 479,117,867,221 with Prime Factorization
| 3 | 479, 117, 867, 221 |
| 13 | 479, 39, 289, 221 |
| 17 | 479, 3, 289, 17 |
| 479, 3, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 479 x 3 x 1 x 17 = 16196427
Therefore, the lowest common multiple of 479,117,867,221 is 16196427.
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.
479 x 117 x 867 x 221 = 10738231101
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.
479 : 1, 479
117 : 1, 3, 9, 13, 39, 117
867 : 1, 3, 17, 51, 289, 867
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,117,867,221, is 1.
Now, the common factors can be found like this.
479:479
117:3x 3x 13
867:3x 17x 17
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 17 = 663
Therefore, the value for common factors is 663.
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 = 10738231101/(1x663)
LCM = 10738231101/663
LCM = 16196427
Thus, we can understand that the LCM of 479,117,867,221 is 16196427.
