Given numbers are 161,771,861,676

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

The LCM of 161,771,861,676 is 3440414796.

Find LCM of 161,771,861,676 with Prime Factorization

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

3 x 7 x 23 x 257 x 41 x 676 = 3440414796

Therefore, the lowest common multiple of 161,771,861,676 is 3440414796.

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 771 x 861 x 676 = 72248710716

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

771 : 1, 3, 257, 771

861 : 1, 3, 7, 21, 41, 123, 287, 861

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,771,861,676, is 1.

Now, the common factors can be found like this.

161:7x 23

771:3x 257

861:3x 7x 41

676:2x 2x 13x 13

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 72248710716/(1x21)

LCM = 72248710716/21

LCM = 3440414796

Thus, we can understand that the LCM of 161,771,861,676 is 3440414796.
