Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 2 x 2 x 3 x 3 x 7 x 1 x 11 x 41 x 10 = 9092160

Therefore, the lowest common multiple of 288,693,861,960 is 9092160.

LCM Formula to Find Lowest Common Multiple of 288,693,861,960

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.

288 x 693 x 861 x 960 = 164968151040

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.

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

861 : 1, 3, 7, 21, 41, 123, 287, 861

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,693,861,960, is 3.

Now, the common factors can be found like this.

288:2x 2x 2x 2x 2x 3x 3

693:3x 3x 7x 11

861:3x 7x 41

960:2x 2x 2x 2x 2x 2x 3x 5

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 3x 3x 3x 7 = 6048

Therefore, the value for common factors is 6048.

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 = 164968151040/(3x6048)

LCM = 164968151040/18144

LCM = 9092160

Thus, we can understand that the LCM of 288,693,861,960 is 9092160.
