Given numbers are 329,245,663,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 329,245,663,221 is 7634445.
Find LCM of 329,245,663,221 with Prime Factorization
| 7 | 329, 245, 663, 221 |
| 13 | 47, 35, 663, 221 |
| 17 | 47, 35, 51, 17 |
| 47, 35, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 17 x 47 x 35 x 3 x 1 = 7634445
Therefore, the lowest common multiple of 329,245,663,221 is 7634445.
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.
329 x 245 x 663 x 221 = 11810486415
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.
329 : 1, 7, 47, 329
245 : 1, 5, 7, 35, 49, 245
663 : 1, 3, 13, 17, 39, 51, 221, 663
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 329,245,663,221, is 1.
Now, the common factors can be found like this.
329:7x 47
245:5x 7x 7
663:3x 13x 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.
7x 13x 17 = 1547
Therefore, the value for common factors is 1547.
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 = 11810486415/(1x1547)
LCM = 11810486415/1547
LCM = 7634445
Thus, we can understand that the LCM of 329,245,663,221 is 7634445.
