Given numbers are 242,128,336,638

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

The LCM of 242,128,336,638 is 9432192.

Find LCM of 242,128,336,638 with Prime Factorization

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

2 x 2 x 2 x 2 x 11 x 11 x 8 x 21 x 29 = 9432192

Therefore, the lowest common multiple of 242,128,336,638 is 9432192.

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.

242 x 128 x 336 x 638 = 6640263168

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.

242 : 1, 2, 11, 22, 121, 242

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

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,128,336,638, is 2.

Now, the common factors can be found like this.

242:2x 11x 11

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

336:2x 2x 2x 2x 3x 7

638:2x 11x 29

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 11 = 352

Therefore, the value for common factors is 352.

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 = 6640263168/(2x352)

LCM = 6640263168/704

LCM = 9432192

Thus, we can understand that the LCM of 242,128,336,638 is 9432192.
