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 1 x 1 x 4 x 691 = 1592064

Therefore, the lowest common multiple of 576,576,256,691 is 1592064.

LCM Formula to Find Lowest Common Multiple of 576,576,256,691

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.

576 x 576 x 256 x 691 = 58689847296

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.

576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576

576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 576,576,256,691, is 1.

Now, the common factors can be found like this.

576:2x 2x 2x 2x 2x 2x 3x 3

576:2x 2x 2x 2x 2x 2x 3x 3

256:2x 2x 2x 2x 2x 2x 2x 2

691:691

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 2x 2x 2x 3x 3 = 36864

Therefore, the value for common factors is 36864.

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 = 58689847296/(1x36864)

LCM = 58689847296/36864

LCM = 1592064

Thus, we can understand that the LCM of 576,576,256,691 is 1592064.
