Find LCM of 555,888,256,742 with Prime Factorization


2 555, 888, 256, 742
2 555, 444, 128, 371
2 555, 222, 64, 371
3 555, 111, 32, 371
37 185, 37, 32, 371
5, 1, 32, 371

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

2 x 2 x 2 x 3 x 37 x 5 x 1 x 32 x 371 = 52711680

Therefore, the lowest common multiple of 555,888,256,742 is 52711680.

LCM Formula to Find Lowest Common Multiple of 555,888,256,742

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.

555 x 888 x 256 x 742 = 93615943680

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.

555 : 1, 3, 5, 15, 37, 111, 185, 555

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

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

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,888,256,742, is 1.

Now, the common factors can be found like this.

555:3x 5x 37

888:2x 2x 2x 3x 37

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

742:2x 7x 53

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 3x 37 = 1776

Therefore, the value for common factors is 1776.

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 = 93615943680/(1x1776)

LCM = 93615943680/1776

LCM = 52711680

Thus, we can understand that the LCM of 555,888,256,742 is 52711680.
