Given numbers are 831,320,695,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,320,695,450 is 554443200.
Find LCM of 831,320,695,450 with Prime Factorization
| 2 | 831, 320, 695, 450 |
| 3 | 831, 160, 695, 225 |
| 5 | 277, 160, 695, 75 |
| 277, 32, 139, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 277 x 32 x 139 x 15 = 554443200
Therefore, the lowest common multiple of 831,320,695,450 is 554443200.
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.
831 x 320 x 695 x 450 = 83166480000
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.
831 : 1, 3, 277, 831
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
695 : 1, 5, 139, 695
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,320,695,450, is 1.
Now, the common factors can be found like this.
831:3x 277
320:2x 2x 2x 2x 2x 2x 5
695:5x 139
450:2x 3x 3x 5x 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 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 83166480000/(1x150)
LCM = 83166480000/150
LCM = 554443200
Thus, we can understand that the LCM of 831,320,695,450 is 554443200.
