| 11 | 11, 157, 77, 3, 124 |
| 1, 157, 7, 3, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 11 x 1 x 157 x 7 x 3 x 124 = 1618958880
Therefore, the lowest common multiple of 990,628,616,135,992 is 1618958880.
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.
990 x 628 x 616 x 135 x 992 = 51288617318400
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.
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
628 : 1, 2, 4, 157, 314, 628
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
135 : 1, 3, 5, 9, 15, 27, 45, 135
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,628,616,135,992, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
628:2x 2x 157
616:2x 2x 2x 7x 11
135:3x 3x 3x 5
992:2x 2x 2x 2x 2x 31
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 2x 2x 3x 3x 5x 11 = 31680
Therefore, the value for common factors is 31680.
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 = 51288617318400/(1x31680)
LCM = 51288617318400/31680
LCM = 1618958880
Thus, we can understand that the LCM of 990,628,616,135,992 is 1618958880.
