Find LCM of 462,264,663,221 with Prime Factorization
2 | 462, 264, 663, 221 |
3 | 231, 132, 663, 221 |
11 | 77, 44, 221, 221 |
13 | 7, 4, 221, 221 |
17 | 7, 4, 17, 17 |
7, 4, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 17 x 7 x 4 x 1 x 1 = 408408
Therefore, the lowest common multiple of 462,264,663,221 is 408408.
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.
462 x 264 x 663 x 221 = 17871117264
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
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 462,264,663,221, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
264:2x 2x 2x 3x 11
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.
2x 3x 3x 11x 13x 17 = 43758
Therefore, the value for common factors is 43758.
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 = 17871117264/(1x43758)
LCM = 17871117264/43758
LCM = 408408
Thus, we can understand that the LCM of 462,264,663,221 is 408408.
