Given numbers are 207,280,161,211

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

The LCM of 207,280,161,211 is 12229560.

Find LCM of 207,280,161,211 with Prime Factorization

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

7 x 23 x 9 x 40 x 1 x 211 = 12229560

Therefore, the lowest common multiple of 207,280,161,211 is 12229560.

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.

207 x 280 x 161 x 211 = 1968959160

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.

207 : 1, 3, 9, 23, 69, 207

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

161 : 1, 7, 23, 161

211 : 1, 211

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,280,161,211, is 1.

Now, the common factors can be found like this.

207:3x 3x 23

280:2x 2x 2x 5x 7

161:7x 23

211:211

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 1968959160/(1x161)

LCM = 1968959160/161

LCM = 12229560

Thus, we can understand that the LCM of 207,280,161,211 is 12229560.
