| 3 | 991, 167, 9, 20, 219 |
| 991, 167, 3, 20, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 991 x 167 x 3 x 20 x 73 = 69588178560
Therefore, the lowest common multiple of 991,668,288,640,876 is 69588178560.
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.
991 x 668 x 288 x 640 x 876 = 106887442268160
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.
991 : 1, 991
668 : 1, 2, 4, 167, 334, 668
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,668,288,640,876, is 1.
Now, the common factors can be found like this.
991:991
668:2x 2x 167
288:2x 2x 2x 2x 2x 3x 3
640:2x 2x 2x 2x 2x 2x 2x 5
876:2x 2x 3x 73
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 2x 2x 2x 3 = 1536
Therefore, the value for common factors is 1536.
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 = 106887442268160/(1x1536)
LCM = 106887442268160/1536
LCM = 69588178560
Thus, we can understand that the LCM of 991,668,288,640,876 is 69588178560.
