Find LCM of 998,255,561,175,825 with Prime Factorization
| 3 | 998, 255, 561, 175, 825 |
| 5 | 998, 85, 187, 175, 275 |
| 5 | 998, 17, 187, 35, 55 |
| 11 | 998, 17, 187, 7, 11 |
| 17 | 998, 17, 17, 7, 1 |
| 998, 1, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 11 x 17 x 998 x 1 x 1 x 7 x 1 = 97978650
Therefore, the lowest common multiple of 998,255,561,175,825 is 97978650.
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.
998 x 255 x 561 x 175 x 825 = 20612258493750
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.
998 : 1, 2, 499, 998
255 : 1, 3, 5, 15, 17, 51, 85, 255
561 : 1, 3, 11, 17, 33, 51, 187, 561
175 : 1, 5, 7, 25, 35, 175
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,255,561,175,825, is 1.
Now, the common factors can be found like this.
998:2x 499
255:3x 5x 17
561:3x 11x 17
175:5x 5x 7
825:3x 5x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 5x 11x 17 = 210375
Therefore, the value for common factors is 210375.
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 = 20612258493750/(1x210375)
LCM = 20612258493750/210375
LCM = 97978650
Thus, we can understand that the LCM of 998,255,561,175,825 is 97978650.
