Given numbers are 239,523,476,128,642

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

The LCM of 239,523,476,128,642 is 611169331584.

Find LCM of 239,523,476,128,642 with Prime Factorization

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

2 x 2 x 239 x 523 x 119 x 32 x 321 = 611169331584

Therefore, the lowest common multiple of 239,523,476,128,642 is 611169331584.

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.

239 x 523 x 476 x 128 x 642 = 4889354652672

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.

239 : 1, 239

523 : 1, 523

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,523,476,128,642, is 1.

Now, the common factors can be found like this.

239:239

523:523

476:2x 2x 7x 17

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

642:2x 3x 107

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 2 = 8

Therefore, the value for common factors is 8.

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 = 4889354652672/(1x8)

LCM = 4889354652672/8

LCM = 611169331584

Thus, we can understand that the LCM of 239,523,476,128,642 is 611169331584.
