Given numbers are 161,571,721,161

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

The LCM of 161,571,721,161 is 9468893.

Find LCM of 161,571,721,161 with Prime Factorization

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

7 x 23 x 1 x 571 x 103 x 1 = 9468893

Therefore, the lowest common multiple of 161,571,721,161 is 9468893.

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 571 x 721 x 161 = 10671442411

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

571 : 1, 571

721 : 1, 7, 103, 721

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,571,721,161, is 1.

Now, the common factors can be found like this.

161:7x 23

571:571

721:7x 103

161:7x 23

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

7x 7x 23 = 1127

Therefore, the value for common factors is 1127.

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 = 10671442411/(1x1127)

LCM = 10671442411/1127

LCM = 9468893

Thus, we can understand that the LCM of 161,571,721,161 is 9468893.
