Given numbers are 161,540,326,414,691

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

The LCM of 161,540,326,414,691 is 9792313020.

Find LCM of 161,540,326,414,691 with Prime Factorization

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

2 x 3 x 3 x 23 x 7 x 30 x 163 x 1 x 691 = 9792313020

Therefore, the lowest common multiple of 161,540,326,414,691 is 9792313020.

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 540 x 326 x 414 x 691 = 8108035180560

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

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

326 : 1, 2, 163, 326

414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,540,326,414,691, is 1.

Now, the common factors can be found like this.

161:7x 23

540:2x 2x 3x 3x 3x 5

326:2x 163

414:2x 3x 3x 23

691:691

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 3x 3x 23 = 828

Therefore, the value for common factors is 828.

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 = 8108035180560/(1x828)

LCM = 8108035180560/828

LCM = 9792313020

Thus, we can understand that the LCM of 161,540,326,414,691 is 9792313020.
