Given numbers are 617,721,738,617

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

The LCM of 617,721,738,617 is 328304466.

Find LCM of 617,721,738,617 with Prime Factorization

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

617 x 1 x 721 x 738 x 1 = 328304466

Therefore, the lowest common multiple of 617,721,738,617 is 328304466.

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.

617 x 721 x 738 x 617 = 202563855522

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.

617 : 1, 617

721 : 1, 7, 103, 721

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

617 : 1, 617

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,721,738,617, is 1.

Now, the common factors can be found like this.

617:617

721:7x 103

738:2x 3x 3x 41

617:617

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

617 = 617

Therefore, the value for common factors is 617.

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 = 202563855522/(1x617)

LCM = 202563855522/617

LCM = 328304466

Thus, we can understand that the LCM of 617,721,738,617 is 328304466.
