Find LCM of 182,900,420,391,255 with Prime Factorization
| 2 | 182, 900, 420, 391, 255 |
| 2 | 91, 450, 210, 391, 255 |
| 3 | 91, 225, 105, 391, 255 |
| 5 | 91, 75, 35, 391, 85 |
| 7 | 91, 15, 7, 391, 17 |
| 17 | 13, 15, 1, 391, 17 |
| 13, 15, 1, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 17 x 13 x 15 x 1 x 23 x 1 = 32022900
Therefore, the lowest common multiple of 182,900,420,391,255 is 32022900.
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.
182 x 900 x 420 x 391 x 255 = 6859305180000
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.
182 : 1, 2, 7, 13, 14, 26, 91, 182
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
391 : 1, 17, 23, 391
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 182,900,420,391,255, is 1.
Now, the common factors can be found like this.
182:2x 7x 13
900:2x 2x 3x 3x 5x 5
420:2x 2x 3x 5x 7
391:17x 23
255:3x 5x 17
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 2x 3x 3x 5x 5x 7x 17 = 214200
Therefore, the value for common factors is 214200.
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 = 6859305180000/(1x214200)
LCM = 6859305180000/214200
LCM = 32022900
Thus, we can understand that the LCM of 182,900,420,391,255 is 32022900.
