Given numbers are 201,138,615,217

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

The LCM of 201,138,615,217 is 411308310.

Find LCM of 201,138,615,217 with Prime Factorization

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

3 x 67 x 46 x 205 x 217 = 411308310

Therefore, the lowest common multiple of 201,138,615,217 is 411308310.

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.

201 x 138 x 615 x 217 = 3701774790

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.

201 : 1, 3, 67, 201

138 : 1, 2, 3, 6, 23, 46, 69, 138

615 : 1, 3, 5, 15, 41, 123, 205, 615

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 201,138,615,217, is 1.

Now, the common factors can be found like this.

201:3x 67

138:2x 3x 23

615:3x 5x 41

217:7x 31

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 3701774790/(1x9)

LCM = 3701774790/9

LCM = 411308310

Thus, we can understand that the LCM of 201,138,615,217 is 411308310.
