Find LCM of 821,902,484,255,459 with Prime Factorization
| 2 | 821, 902, 484, 255, 459 |
| 3 | 821, 451, 242, 255, 459 |
| 11 | 821, 451, 242, 85, 153 |
| 17 | 821, 41, 22, 85, 153 |
| 821, 41, 22, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 821 x 41 x 22 x 5 x 9 = 37389965580
Therefore, the lowest common multiple of 821,902,484,255,459 is 37389965580.
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.
821 x 902 x 484 x 255 x 459 = 41951541380760
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.
821 : 1, 821
902 : 1, 2, 11, 22, 41, 82, 451, 902
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
255 : 1, 3, 5, 15, 17, 51, 85, 255
459 : 1, 3, 9, 17, 27, 51, 153, 459
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,902,484,255,459, is 1.
Now, the common factors can be found like this.
821:821
902:2x 11x 41
484:2x 2x 11x 11
255:3x 5x 17
459:3x 3x 3x 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 3x 11x 17 = 1122
Therefore, the value for common factors is 1122.
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 = 41951541380760/(1x1122)
LCM = 41951541380760/1122
LCM = 37389965580
Thus, we can understand that the LCM of 821,902,484,255,459 is 37389965580.
