Find LCM of 317,210,201,644,521 with Prime Factorization
2 | 317, 210, 201, 644, 521 |
3 | 317, 105, 201, 322, 521 |
7 | 317, 35, 67, 322, 521 |
317, 5, 67, 46, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 317 x 5 x 67 x 46 x 521 = 106892913540
Therefore, the lowest common multiple of 317,210,201,644,521 is 106892913540.
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.
317 x 210 x 201 x 644 x 521 = 4489502368680
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.
317 : 1, 317
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
201 : 1, 3, 67, 201
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,210,201,644,521, is 1.
Now, the common factors can be found like this.
317:317
210:2x 3x 5x 7
201:3x 67
644:2x 2x 7x 23
521:521
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 7 = 42
Therefore, the value for common factors is 42.
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 = 4489502368680/(1x42)
LCM = 4489502368680/42
LCM = 106892913540
Thus, we can understand that the LCM of 317,210,201,644,521 is 106892913540.
