Given numbers are 654,384,128,478,842

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 654,384,128,478,842 is 4211508864.

Find LCM of 654,384,128,478,842 with Prime Factorization

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 3 x 109 x 1 x 1 x 239 x 421 = 4211508864

Therefore, the lowest common multiple of 654,384,128,478,842 is 4211508864.

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.

654 x 384 x 128 x 478 x 842 = 12937755230208

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

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

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

478 : 1, 2, 239, 478

842 : 1, 2, 421, 842

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,384,128,478,842, is 2.

Now, the common factors can be found like this.

654:2x 3x 109

384:2x 2x 2x 2x 2x 2x 2x 3

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

478:2x 239

842:2x 421

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 3 = 1536

Therefore, the value for common factors is 1536.

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 = 12937755230208/(2x1536)

LCM = 12937755230208/3072

LCM = 4211508864

Thus, we can understand that the LCM of 654,384,128,478,842 is 4211508864.
