Given numbers are 419,535,321,721

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

The LCM of 419,535,321,721 is 484868895.

Find LCM of 419,535,321,721 with Prime Factorization

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

107 x 419 x 5 x 3 x 721 = 484868895

Therefore, the lowest common multiple of 419,535,321,721 is 484868895.

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.

419 x 535 x 321 x 721 = 51880971765

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.

419 : 1, 419

535 : 1, 5, 107, 535

321 : 1, 3, 107, 321

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,535,321,721, is 1.

Now, the common factors can be found like this.

419:419

535:5x 107

321:3x 107

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.

107 = 107

Therefore, the value for common factors is 107.

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 = 51880971765/(1x107)

LCM = 51880971765/107

LCM = 484868895

Thus, we can understand that the LCM of 419,535,321,721 is 484868895.
