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

2 x 2 x 2 x 2 x 3 x 5 x 16 x 121 x 67 x 5 = 155654400

Therefore, the lowest common multiple of 768,605,804,400 is 155654400.

LCM Formula to Find Lowest Common Multiple of 768,605,804,400

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.

768 x 605 x 804 x 400 = 149428224000

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.

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

605 : 1, 5, 11, 55, 121, 605

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,605,804,400, is 1.

Now, the common factors can be found like this.

768:2x 2x 2x 2x 2x 2x 2x 2x 3

605:5x 11x 11

804:2x 2x 3x 67

400:2x 2x 2x 2x 5x 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 2x 3x 5 = 960

Therefore, the value for common factors is 960.

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 = 149428224000/(1x960)

LCM = 149428224000/960

LCM = 155654400

Thus, we can understand that the LCM of 768,605,804,400 is 155654400.
