Given numbers are 158,464,128,557

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

The LCM of 158,464,128,557 is 163339136.

Find LCM of 158,464,128,557 with Prime Factorization

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

2 x 2 x 2 x 2 x 79 x 29 x 8 x 557 = 163339136

Therefore, the lowest common multiple of 158,464,128,557 is 163339136.

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.

158 x 464 x 128 x 557 = 5226852352

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.

158 : 1, 2, 79, 158

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

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

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,464,128,557, is 1.

Now, the common factors can be found like this.

158:2x 79

464:2x 2x 2x 2x 29

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

557:557

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 2 = 32

Therefore, the value for common factors is 32.

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 = 5226852352/(1x32)

LCM = 5226852352/32

LCM = 163339136

Thus, we can understand that the LCM of 158,464,128,557 is 163339136.
