Given numbers are 128,145,349,948

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

The LCM of 128,145,349,948 is 1535153280.

Find LCM of 128,145,349,948 with Prime Factorization

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

2 x 2 x 32 x 145 x 349 x 237 = 1535153280

Therefore, the lowest common multiple of 128,145,349,948 is 1535153280.

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 145 x 349 x 948 = 6140613120

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

145 : 1, 5, 29, 145

349 : 1, 349

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,145,349,948, is 1.

Now, the common factors can be found like this.

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

145:5x 29

349:349

948:2x 2x 3x 79

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 = 6140613120/(1x4)

LCM = 6140613120/4

LCM = 1535153280

Thus, we can understand that the LCM of 128,145,349,948 is 1535153280.
