Find LCM of 916,644,723,990,750 with Prime Factorization
| 2 | 916, 644, 723, 990, 750 |
| 2 | 458, 322, 723, 495, 375 |
| 3 | 229, 161, 723, 495, 375 |
| 5 | 229, 161, 241, 165, 125 |
| 229, 161, 241, 33, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 229 x 161 x 241 x 33 x 25 = 439828735500
Therefore, the lowest common multiple of 916,644,723,990,750 is 439828735500.
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.
916 x 644 x 723 x 990 x 750 = 316676689560000
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.
916 : 1, 2, 4, 229, 458, 916
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
723 : 1, 3, 241, 723
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,644,723,990,750, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
644:2x 2x 7x 23
723:3x 241
990:2x 3x 3x 5x 11
750:2x 3x 5x 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 2x 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 316676689560000/(1x720)
LCM = 316676689560000/720
LCM = 439828735500
Thus, we can understand that the LCM of 916,644,723,990,750 is 439828735500.
