Find LCM of 258,402,315,486,145 with Prime Factorization
2 | 258, 402, 315, 486, 145 |
3 | 129, 201, 315, 243, 145 |
3 | 43, 67, 105, 81, 145 |
5 | 43, 67, 35, 27, 145 |
43, 67, 7, 27, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 43 x 67 x 7 x 27 x 29 = 1421168490
Therefore, the lowest common multiple of 258,402,315,486,145 is 1421168490.
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.
258 x 402 x 315 x 486 x 145 = 2302292953800
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
402 : 1, 2, 3, 6, 67, 134, 201, 402
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,402,315,486,145, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
402:2x 3x 67
315:3x 3x 5x 7
486:2x 3x 3x 3x 3x 3
145:5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3x 5 = 1620
Therefore, the value for common factors is 1620.
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 = 2302292953800/(1x1620)
LCM = 2302292953800/1620
LCM = 1421168490
Thus, we can understand that the LCM of 258,402,315,486,145 is 1421168490.
