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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 9 x 289 x 611 x 581 = 118186443648

Therefore, the lowest common multiple of 128,576,289,611,581 is 118186443648.

LCM Formula to Find Lowest Common Multiple of 128,576,289,611,581

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.

128 x 576 x 289 x 611 x 581 = 7563932393472

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.

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

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

289 : 1, 17, 289

611 : 1, 13, 47, 611

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,576,289,611,581, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

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

289:17x 17

611:13x 47

581:7x 83

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 2 = 64

Therefore, the value for common factors is 64.

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 = 7563932393472/(1x64)

LCM = 7563932393472/64

LCM = 118186443648

Thus, we can understand that the LCM of 128,576,289,611,581 is 118186443648.
