Given numbers are 717,220,621,921

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

The LCM of 717,220,621,921 is 10024219260.

Find LCM of 717,220,621,921 with Prime Factorization

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

3 x 239 x 220 x 207 x 307 = 10024219260

Therefore, the lowest common multiple of 717,220,621,921 is 10024219260.

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.

717 x 220 x 621 x 921 = 90217973340

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.

717 : 1, 3, 239, 717

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

621 : 1, 3, 9, 23, 27, 69, 207, 621

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,220,621,921, is 1.

Now, the common factors can be found like this.

717:3x 239

220:2x 2x 5x 11

621:3x 3x 3x 23

921:3x 307

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 = 90217973340/(1x9)

LCM = 90217973340/9

LCM = 10024219260

Thus, we can understand that the LCM of 717,220,621,921 is 10024219260.
