Find LCM of 165,209,494,210 with Prime Factorization
2 | 165, 209, 494, 210 |
3 | 165, 209, 247, 105 |
5 | 55, 209, 247, 35 |
11 | 11, 209, 247, 7 |
19 | 1, 19, 247, 7 |
1, 1, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 19 x 1 x 1 x 13 x 7 = 570570
Therefore, the lowest common multiple of 165,209,494,210 is 570570.
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.
165 x 209 x 494 x 210 = 3577473900
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
209 : 1, 11, 19, 209
494 : 1, 2, 13, 19, 26, 38, 247, 494
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,209,494,210, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
209:11x 19
494:2x 13x 19
210:2x 3x 5x 7
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 5x 11x 19 = 6270
Therefore, the value for common factors is 6270.
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 = 3577473900/(1x6270)
LCM = 3577473900/6270
LCM = 570570
Thus, we can understand that the LCM of 165,209,494,210 is 570570.
