The LCM of 46,22,56,63,990 is 637560.
Find LCM of 46,22,56,63,990 with Prime Factorization
| 2 | 46, 22, 56, 63, 990 |
| 3 | 23, 11, 28, 63, 495 |
| 3 | 23, 11, 28, 21, 165 |
| 7 | 23, 11, 28, 7, 55 |
| 11 | 23, 11, 4, 1, 55 |
| 23, 1, 4, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 11 x 23 x 1 x 4 x 1 x 5 = 637560
Therefore, the lowest common multiple of 46,22,56,63,990 is 637560.
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.
46 x 22 x 56 x 63 x 990 = 3534632640
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.
46 : 1, 2, 23, 46
22 : 1, 2, 11, 22
56 : 1, 2, 4, 7, 8, 14, 28, 56
63 : 1, 3, 7, 9, 21, 63
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 46,22,56,63,990, is 1.
Now, the common factors can be found like this.
46:2x 23
22:2x 11
56:2x 2x 2x 7
63:3x 3x 7
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 3x 7x 11 = 5544
Therefore, the value for common factors is 5544.
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 = 3534632640/(1x5544)
LCM = 3534632640/5544
LCM = 637560
Thus, we can understand that the LCM of 46,22,56,63,990 is 637560.
