Find LCM of 802,535,135,405,840 with Prime Factorization
| 2 | 802, 535, 135, 405, 840 |
| 3 | 401, 535, 135, 405, 420 |
| 3 | 401, 535, 45, 135, 140 |
| 3 | 401, 535, 15, 45, 140 |
| 5 | 401, 535, 5, 15, 140 |
| 401, 107, 1, 3, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 401 x 107 x 1 x 3 x 28 = 973130760
Therefore, the lowest common multiple of 802,535,135,405,840 is 973130760.
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.
802 x 535 x 135 x 405 x 840 = 19705897890000
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.
802 : 1, 2, 401, 802
535 : 1, 5, 107, 535
135 : 1, 3, 5, 9, 15, 27, 45, 135
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,535,135,405,840, is 1.
Now, the common factors can be found like this.
802:2x 401
535:5x 107
135:3x 3x 3x 5
405:3x 3x 3x 3x 5
840:2x 2x 2x 3x 5x 7
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 3x 5x 5x 5 = 20250
Therefore, the value for common factors is 20250.
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 = 19705897890000/(1x20250)
LCM = 19705897890000/20250
LCM = 973130760
Thus, we can understand that the LCM of 802,535,135,405,840 is 973130760.
