Find LCM of 851,990,715,717,270 with Prime Factorization
| 2 | 851, 990, 715, 717, 270 |
| 3 | 851, 495, 715, 717, 135 |
| 3 | 851, 165, 715, 239, 45 |
| 5 | 851, 55, 715, 239, 15 |
| 11 | 851, 11, 143, 239, 3 |
| 851, 1, 13, 239, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 851 x 1 x 13 x 239 x 3 = 7852849290
Therefore, the lowest common multiple of 851,990,715,717,270 is 7852849290.
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.
851 x 990 x 715 x 717 x 270 = 116614811956500
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.
851 : 1, 23, 37, 851
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
715 : 1, 5, 11, 13, 55, 65, 143, 715
717 : 1, 3, 239, 717
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,990,715,717,270, is 1.
Now, the common factors can be found like this.
851:23x 37
990:2x 3x 3x 5x 11
715:5x 11x 13
717:3x 239
270:2x 3x 3x 3x 5
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 3x 3x 5x 5x 11 = 14850
Therefore, the value for common factors is 14850.
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 = 116614811956500/(1x14850)
LCM = 116614811956500/14850
LCM = 7852849290
Thus, we can understand that the LCM of 851,990,715,717,270 is 7852849290.
