Given numbers are 161,361,541,903

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

The LCM of 161,361,541,903 is 4056206469.

Find LCM of 161,361,541,903 with Prime Factorization

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

7 x 23 x 361 x 541 x 129 = 4056206469

Therefore, the lowest common multiple of 161,361,541,903 is 4056206469.

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 361 x 541 x 903 = 28393445283

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

361 : 1, 19, 361

541 : 1, 541

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,361,541,903, is 1.

Now, the common factors can be found like this.

161:7x 23

361:19x 19

541:541

903:3x 7x 43

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

7 = 7

Therefore, the value for common factors is 7.

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 = 28393445283/(1x7)

LCM = 28393445283/7

LCM = 4056206469

Thus, we can understand that the LCM of 161,361,541,903 is 4056206469.
