| 197, 109, 16, 689, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 197 x 109 x 16 x 689 x 3 = 102262328064
Therefore, the lowest common multiple of 197,981,768,689,432 is 102262328064.
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.
197 x 981 x 768 x 689 x 432 = 44177325723648
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.
197 : 1, 197
981 : 1, 3, 9, 109, 327, 981
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
689 : 1, 13, 53, 689
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,981,768,689,432, is 1.
Now, the common factors can be found like this.
197:197
981:3x 3x 109
768:2x 2x 2x 2x 2x 2x 2x 2x 3
689:13x 53
432:2x 2x 2x 2x 3x 3x 3
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 44177325723648/(1x432)
LCM = 44177325723648/432
LCM = 102262328064
Thus, we can understand that the LCM of 197,981,768,689,432 is 102262328064.
