Given numbers are 161,554,863,438

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

The LCM of 161,554,863,438 is 16857398418.

Find LCM of 161,554,863,438 with Prime Factorization

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

2 x 161 x 277 x 863 x 219 = 16857398418

Therefore, the lowest common multiple of 161,554,863,438 is 16857398418.

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.

161 x 554 x 863 x 438 = 33714796836

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.

161 : 1, 7, 23, 161

554 : 1, 2, 277, 554

863 : 1, 863

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,554,863,438, is 1.

Now, the common factors can be found like this.

161:7x 23

554:2x 277

863:863

438:2x 3x 73

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

2 = 2

Therefore, the value for common factors is 2.

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 = 33714796836/(1x2)

LCM = 33714796836/2

LCM = 16857398418

Thus, we can understand that the LCM of 161,554,863,438 is 16857398418.
