Given numbers are 488,173,663,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 488,173,663,221 is 55973112.
Find LCM of 488,173,663,221 with Prime Factorization
13 | 488, 173, 663, 221 |
17 | 488, 173, 51, 17 |
488, 173, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 488 x 173 x 3 x 1 = 55973112
Therefore, the lowest common multiple of 488,173,663,221 is 55973112.
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.
488 x 173 x 663 x 221 = 12370057752
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.
488 : 1, 2, 4, 8, 61, 122, 244, 488
173 : 1, 173
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 488,173,663,221, is 1.
Now, the common factors can be found like this.
488:2x 2x 2x 61
173:173
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.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 12370057752/(1x221)
LCM = 12370057752/221
LCM = 55973112
Thus, we can understand that the LCM of 488,173,663,221 is 55973112.
