Given numbers are 431,201,299,721,721

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

The LCM of 431,201,299,721,721 is 18675824349.

Find LCM of 431,201,299,721,721 with Prime Factorization

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

7 x 103 x 431 x 201 x 299 x 1 x 1 = 18675824349

Therefore, the lowest common multiple of 431,201,299,721,721 is 18675824349.

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.

431 x 201 x 299 x 721 x 721 = 13465269355629

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.

431 : 1, 431

201 : 1, 3, 67, 201

299 : 1, 13, 23, 299

721 : 1, 7, 103, 721

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,201,299,721,721, is 1.

Now, the common factors can be found like this.

431:431

201:3x 67

299:13x 23

721:7x 103

721:7x 103

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

7x 103 = 721

Therefore, the value for common factors is 721.

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 = 13465269355629/(1x721)

LCM = 13465269355629/721

LCM = 18675824349

Thus, we can understand that the LCM of 431,201,299,721,721 is 18675824349.
