Given numbers are 221,133,260,230,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,133,260,230,394 is 2663593660.
Find LCM of 221,133,260,230,394 with Prime Factorization
2 | 221, 133, 260, 230, 394 |
5 | 221, 133, 130, 115, 197 |
13 | 221, 133, 26, 23, 197 |
17, 133, 2, 23, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 17 x 133 x 2 x 23 x 197 = 2663593660
Therefore, the lowest common multiple of 221,133,260,230,394 is 2663593660.
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.
221 x 133 x 260 x 230 x 394 = 692534351600
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.
221 : 1, 13, 17, 221
133 : 1, 7, 19, 133
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
230 : 1, 2, 5, 10, 23, 46, 115, 230
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,133,260,230,394, is 1.
Now, the common factors can be found like this.
221:13x 17
133:7x 19
260:2x 2x 5x 13
230:2x 5x 23
394:2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 692534351600/(1x260)
LCM = 692534351600/260
LCM = 2663593660
Thus, we can understand that the LCM of 221,133,260,230,394 is 2663593660.
