| 3 | 33, 83, 63, 5, 2 |
| 11, 83, 21, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 x 11 x 83 x 21 x 5 x 2 = 110436480
Therefore, the lowest common multiple of 198,249,756,960,128 is 110436480.
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.
198 x 249 x 756 x 960 x 128 = 4580021698560
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
249 : 1, 3, 83, 249
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,249,756,960,128, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
249:3x 83
756:2x 2x 3x 3x 3x 7
960:2x 2x 2x 2x 2x 2x 3x 5
128:2x 2x 2x 2x 2x 2x 2
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 3x 3x 3x 3 = 41472
Therefore, the value for common factors is 41472.
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 = 4580021698560/(1x41472)
LCM = 4580021698560/41472
LCM = 110436480
Thus, we can understand that the LCM of 198,249,756,960,128 is 110436480.
