The LCM of 52,40,33,31,990 is 1595880.
Find LCM of 52,40,33,31,990 with Prime Factorization
| 2 | 52, 40, 33, 31, 990 |
| 2 | 26, 20, 33, 31, 495 |
| 3 | 13, 10, 33, 31, 495 |
| 5 | 13, 10, 11, 31, 165 |
| 11 | 13, 2, 11, 31, 33 |
| 13, 2, 1, 31, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 13 x 2 x 1 x 31 x 3 = 1595880
Therefore, the lowest common multiple of 52,40,33,31,990 is 1595880.
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.
52 x 40 x 33 x 31 x 990 = 2106561600
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.
52 : 1, 2, 4, 13, 26, 52
40 : 1, 2, 4, 5, 8, 10, 20, 40
33 : 1, 3, 11, 33
31 : 1, 31
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 52,40,33,31,990, is 1.
Now, the common factors can be found like this.
52:2x 2x 13
40:2x 2x 2x 5
33:3x 11
31:31
990:2x 3x 3x 5x 11
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 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 2106561600/(1x1320)
LCM = 2106561600/1320
LCM = 1595880
Thus, we can understand that the LCM of 52,40,33,31,990 is 1595880.
