Given numbers are 128,239,226,838

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

The LCM of 128,239,226,838 is 1448439424.

Find LCM of 128,239,226,838 with Prime Factorization

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

2 x 64 x 239 x 113 x 419 = 1448439424

Therefore, the lowest common multiple of 128,239,226,838 is 1448439424.

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.

128 x 239 x 226 x 838 = 5793757696

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.

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

239 : 1, 239

226 : 1, 2, 113, 226

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,239,226,838, is 1.

Now, the common factors can be found like this.

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

239:239

226:2x 113

838:2x 419

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 5793757696/(1x4)

LCM = 5793757696/4

LCM = 1448439424

Thus, we can understand that the LCM of 128,239,226,838 is 1448439424.
