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 1 x 397 x 2 x 619 = 62910208

Therefore, the lowest common multiple of 256,397,128,619 is 62910208.

LCM Formula to Find Lowest Common Multiple of 256,397,128,619

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.

256 x 397 x 128 x 619 = 8052506624

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.

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

397 : 1, 397

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

619 : 1, 619

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,397,128,619, is 1.

Now, the common factors can be found like this.

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

397:397

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

619:619

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 2 = 128

Therefore, the value for common factors is 128.

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 = 8052506624/(1x128)

LCM = 8052506624/128

LCM = 62910208

Thus, we can understand that the LCM of 256,397,128,619 is 62910208.
