Find LCM of 170,475,390,489,702 with Prime Factorization
2 | 170, 475, 390, 489, 702 |
3 | 85, 475, 195, 489, 351 |
5 | 85, 475, 65, 163, 117 |
13 | 17, 95, 13, 163, 117 |
17, 95, 1, 163, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 17 x 95 x 1 x 163 x 9 = 923989950
Therefore, the lowest common multiple of 170,475,390,489,702 is 923989950.
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.
170 x 475 x 390 x 489 x 702 = 10810682415000
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
475 : 1, 5, 19, 25, 95, 475
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
489 : 1, 3, 163, 489
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,475,390,489,702, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
475:5x 5x 19
390:2x 3x 5x 13
489:3x 163
702:2x 3x 3x 3x 13
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 5x 5x 13 = 11700
Therefore, the value for common factors is 11700.
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 = 10810682415000/(1x11700)
LCM = 10810682415000/11700
LCM = 923989950
Thus, we can understand that the LCM of 170,475,390,489,702 is 923989950.
