Find LCM of 281,939,425,135,221 with Prime Factorization
3 | 281, 939, 425, 135, 221 |
5 | 281, 313, 425, 45, 221 |
17 | 281, 313, 85, 9, 221 |
281, 313, 5, 9, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 281 x 313 x 5 x 9 x 13 = 13120388775
Therefore, the lowest common multiple of 281,939,425,135,221 is 13120388775.
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.
281 x 939 x 425 x 135 x 221 = 3345699137625
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.
281 : 1, 281
939 : 1, 3, 313, 939
425 : 1, 5, 17, 25, 85, 425
135 : 1, 3, 5, 9, 15, 27, 45, 135
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,939,425,135,221, is 1.
Now, the common factors can be found like this.
281:281
939:3x 313
425:5x 5x 17
135:3x 3x 3x 5
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 5x 17 = 255
Therefore, the value for common factors is 255.
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 = 3345699137625/(1x255)
LCM = 3345699137625/255
LCM = 13120388775
Thus, we can understand that the LCM of 281,939,425,135,221 is 13120388775.
